Well, it all boils down to this I guess....... The chart says "Not to be extrapolated". You decide to extrapolate. Fair enuf, your decision. Ask yourself this tho, if you f*ck it up, and survive, who they gonna come after????? Don't get me wrong, I'm all for people making their own INFORMED decisions, as long as they are prepared to wear the consequences of THEIR OWN actions. Especially in the old US of A. It is, after all, your decision.
