what does this mean on the TMT list?

H268R-M/L H269 (95%) 320 338 1.16 166 AT NAR 29/360
^^^^^^
I had thought it might mean 95% of a full H load, but then this should be
100% (I think) since the N-sec is shown to be 320.
So what does the 95% really mean?
SIA, if the cut/pasted table out of the TMT list doesn't post right.

Quoted total impulse is 313Ns, which *is* 95% H. I am guessing whoever wrote the page, for whatever reason, used the AT quoted impulse.

NAR have it certified as 320Ns:

Sorry, hit send by accident.
NAR have it certified as 320Ns, but no datasheet. IIRC the videos of the test firing are on

Thanks, though I still wonder a bit since 313/320 is actually closer to 98%.
Weird in any case, since they don't publish the 313 in their table.

I make 313-160=153, 153/160=0.95625 so perhaps 96% is more correct. Still, by the time you figure in random motor variations, what difference does it make :)

You're right in both cases. It doesn't really make a difference other than to understand what their numbers. Since they neither explicitly state what the % number is nor publish the 313, its hard to substantiate the one's intuition as to the meaning.
