Yeah well, my guns are so consistant I use a special chrono that does inches per second. All my guns shoot 3420 IPS +/- 1 over my chrono.

+/- 5
so if a gun is chrono'd at 275, you are saying that for 7-10 shots, it physically cannot be shooting from 270-280 for every shot?

+/- 5 is a number that I'm happy with, but i've SEEN and OWNED guns that were shooting +/-3, never a +/-1 that some people claim... especially the ones with CP regs...

any gun that is shooting ball-on-ball ropes is shooting with very consistent velocity.

if the gun was inconsistent over the chrono, you'd get some balls shooting short and some shooting longer... even some curving sometimes(due to spikes in velocity).

id have to say my droid is +/-5fps cause its ball-on-ball.

this is exactly what im talking about. I bet his guns are always freshly teched before he puts em on bst and only shoots a half a pod of reballs through them before they sit on bst for 10 months....

let me guess fargballen chronos your angels for you?

It was +/- 10-15fps.

Once I get a 2 liter and scm 3 on my timmy, I guess I will see what the consistence is.

CockerPunk and I did a pretty extensive barrel to paint match test - it involved shooting 500 paintballs over a Shooting Chrony - which is an optical chrono and accurate to +/- %.5 - so that means +/- .75 fps at 300 fps.

http://www.pbnation.com/showthread.php?t=2735889

The consistency from the gun was in large part based on paint to barrel match. both under-boring and over-boring gave more consistent results. This was as a trade off for efficiency (average fps per shot).

The best string of 20 shots (and to really make a good claim you need to do samples more on the size of our test - telling us what 5 shots chronoed at isn't a large enough sample to make a blanket statement about a gun) we got was +/- 3fps over 20 shots. With the same gun, tank and paint we got another string of 20 shots with a +/- 11fps swing.

The red RadaChrons that you see at fields are supposed to be withing %1 - so 3 fps at 300 fps.

I would love to see people post up honest lists of 20 shots. I don't need to see videos - I think we can trust each other. I think that it's worth doing with your gun - it can be an eye opener. We learned that the paint to barrel match made what was a poor sounding performance (+/-11) into a fantastic one (+/-3).

seriously... guy with DM i dont mean to hate but i have a gameface vexor i used to use and it was better than +/- 10(with co2).... lol find someone to see if they can improve your consistency cuz thats not normal. anyways i had a spyder electra acs got +/-7ish i think and i have have a VS3 still that gets consistently +/- 7 or less(this one is fininky in the heat...) pmr gets +/-5 so sry yuik(my bad if misspelled) your guns are not tuned properly
rant=fail

edit: i have a mini black magic w/ ccm pump kit, has a black magic reg gets below +/- 5

all my guns are stock except for a ccm on/off and bolt on black magic, and cp on/off on pmr

barrels:
vexor: .689 system x
electra: stock barrel (mine was amazing for some wierd reason nearly as accurate as with the freak w/ .689 insert)
vs3: freak w/ .689
black magic: stock barrel (idk if upgraded got it from a friend)

The first time I chrono my Banshee once I've got it working, I'll have my DV cam with me and make sure I record the readings. It's def. possible.

I used to get +/- 3 fps consistantly with my old 99 Angel SE (which I bought when it was new), and had a Raceframed Ripper cocker with a gen 1 Gladiator giving me a very strange pattern... 278 278 270... 280 280 269, etc. It was almost always 2 at the same velocity, and 3rd shot low. I saw both of these spectacles at multiple different fields, with multiple different red Radarchrons.

I'll admit, it never checked consistence, constantly, but in general it was not +/-2fps or other ridiculous claims people make.

heres the real question.

how do you define your +/- confidence interval?

if i use a 99% model, then my gun need to shoot less than +/- 1 for a string 2- or 30 shots to get a +/- 5 FPS rating.

if you use a 95% model then you need to shoot +/- 2.2 for a 20 shot string to get +/- 5 FPS rating.



since most poeple take 3 shots over the chrono and they range in the +/- 5 range, they say there gun is shooting +/- 5, when in reality we can see that there gun is acutally shooting (according to the 99% model), like +/- 30 FPS.

if you truly want to know what you gun shoots as far as consistency, you need to blast though AT LEAST a couple hundred over the chrono, recording every shot.

as i have done here with the impressive beast of a gun, the EMag - http://www.youtube.com/watch?v=mpUTWDY5NFE

if you look at the spread sheet, you can see that even though the std div of some of the setups were 1.8 FPS that still only means the gun was shooting +/- 5 FPS, and thats with strings of 20ish shots, where everyone but 2 shots were 291 fps.

that gun is a machine, and i have NEVER seen another gun even come close to that as far as chrono consistency.

so guys, it matter of how you define your +/- 5 FPS claims. if you take 3 shots and they are +/-5 that doesn't mean your gun is +/- 5, its more like +/- 30 FPS. whereas if you spend an hour over the chrono and take a few more samples, then your confendince interval gets a bit more accurate.

but according to the definition around here, my Emag was shooting +/- 0 FPS, but anyone with any sense at all would just shake there head.

the mythical +/- 5 FPS gun (according to any REAL model) is truly rare indeed. me and bryce have spent over 8 hours now with eveyr gun you can think of, over a chrono and NONE of them could shoot +/- 5 even with the EMag blasting 10-20 shoots IN A ROW all the same speed. thats still not +/- 5 FPS.

Yeah, CP and I are trying to do something that really hasn't been done in the public eye - attempt actual, well designed and executed tests on paintball stuff.

I would like to propose a challenge to people out there - send us your chrono results. I would love to see what guns / barrel / reg combinations are capable of.

I would like the following:

Marker, barrel, upgrades
Paint brand
Chrono type
A list of 20 or more shots listed in order over the chrono

I know that most of you reading this are speedball players - and I know that you use way more balls off the break than I'm asking you to shoot over the chronograph. It'll only take 2 or three minutes and I would love to see the results.

Post up or PM me.

When you chart your shots, and actually shoot a decent number, like 20 - 30 you will find +/- 5-7 is very very good... and better than most guns can do (unless you throw out one or two freak shots).

I have seen accuracy ratings for chronos... cant find any now, but it seems like I remember 98% on one.

optical chronographs like the Shooting Chrony are %99.5 (or +/- .75 fps @ 300
Red Box radarchrons are %99 accurate (or +/- 1.5 fps @ 300)
