A 4 shot difference? Is that a significant difference?

I would like to point out that 4 shots may not be a significant difference, the fact that manufactures are adopting different theories and implementing them into paintballing shows that there is still more to be learned and done with guns.

He's right to ask though, depending on how other tests fared, a 4 shot difference could very well be within the margin of error. Bryce says that other tests were dead on with those values, and I believe that... but I would still like to see the results of other tests as well.

Regarding that wave theory, considering other guns 'work' on SLP too, why don't they achieve better efficiency.

I found somewhere that the SLPs have better efficiency because they output 275psi. Thus the backpressure in the tank isn't less than the pressure outputted. Therefore with a reg outputting 850 psi, you would start to see shootdown after your gauge reads <850. Whereas with an SLP, you wouldn't start to see shootdown until 275psi.

That theory above is far fetched, but it made sense when someone said it. Also to add to that, I know guns work on 180psi most of the time, but I don't feel that a reg that's supposed to output 850psi could fare well when the backpressure is less than that. I just feel like it wouldn't recharge as fast and that's what made the theory believable.

However I say we boycott ninja products until they tell us.

ninja told us other guns do, mostly other poppet valve guns do.

has not been tested to my knowledge though.

Sounds like the principle of impedance matching in electronics; less return loss the closer the pressures match tank-to-reg-to-marker. Maybe?

What does that efficiency difference mean in terms of a 68/45 tank? if its anything less then a pod who cares?

Also you're gun only needs to be as efficient as you are far away from a fill station.

Example: You shoot 3 pods & hopper in X-ball point.. air station is in pit, you're golden!
You shoot 12+ pods in a nppl 7-man game, refill after each game... gun type & tank size start to matter. (ie your etha & 68/45 wont cut it)
You play all day out in woods & they don't have a fill station.. better get an efficient gun or a 2nd tank!

difference based on this test is theoretical 2402 shots from a perfect 4.5k fill on a 68 tank with the SLP and 2307 with the standard reg. You're looking at just under a pod - less with a non-perfect fill.

Hmm, sounds like some real world testing should be done.

That test was based off a real world test.

right, it's a theoretical total based on real world testing.

I know that this thread has kind of moved beyond here at this point but, I just wanted to throw in my two bits about bernouli's principle. I'm no professional, but I am currently in a physics class and as far as I know Bernoulli's principle does not apply to gas under high pressures.

[xincognitopbx]

I dont know if im right, but i think that gas when its entering/going through the barrel, isnt really that high of presssure at all and thats why it applies.

still theoretical, only real way to know is to do it.

We already know.
