We know that the NFPA codes say. What we don't know is the complete
TMT test results.
FYI, expectation is a mathematical term used extensively in the field
of optimal estimation.
What? Please post a link to comparable TMT cert data so that I can
compare the two.
Just to be clear, I'm not satisfied with just pass/fail testing
results.

"Since Mr. Kelly's *main purpose* here is to 'build the image' that I am
capable of more 'violations' than he is (I've now got TWO 'black marks'
to his ONE), we can just forget about *HIS* 'violation' that started
this whole thing. One of his *most typical* tactics - when painted into
a corner, the classic (and child-like) approach is to say, "Ooooh, look
over there!!" (to distract attention from the fact that he got caught
with his hand in the 'cookie jar')."

"If you fail to think ahead to the possible consequences of your
actions, you're acting on the level of conciousness of apes and small
children. If you know the consequences, and fail to do something to
ensure those consequences are desirable or at least tolerable, then
you're part of the problem. Those who are doing something (even if only
spreading the word at this stage) are those you rail against -- which
would seem to put you in one of the first two categories."

Opinion, the whole thing. <mail to: snipped-for-privacy@gte.net>
And he's unwilling to accept that the rest of TRA's membership doesn't
agree with his definition of "better".
So does the fact that you disagree with TRA mean that TRA is "corrupt"
or evil, and that people should spend all their time bitching about it
like Bob and Jerry do?
I agree that thrust curves are necessary. I don't see the need for
anything more detailed when it comes to delays. By law there can be up
to 20 percent variation in the delays. Providing the test data won't
change that fact. If you need more precision than that, you should be
using electronics.
BTW, Bob has claimed that some delays on motors which were tested by
NAR came out significantly different than the manufacturer's
designation. If that's the case, why did NAR cert them? They should
have either failed the cert, or required the manufacturer to change the
designation to fit the actual performance of the delay.
They do. Phil's talking about user error, which is the most likely
cause of most delay problems.

The packaging of the motors was updated to sho the aerotech designation, and
the NAR S&T designation. Alas this too results in confision,b ecause the
F39-6 tests as an F39-3 and the F39-9 tests as an F39-6.
So when I say "F39-6", which one am I talking about?
