Very interesting, however it is hard to fathom this whole issue revolves around a 2%? difference of compressiblity at 400F?, if I digested your details correctly, and I have little knowledge on the this subject to dispute them in the first place. Would not be the first time we get lost in the weeds.
Reality check, that half the population is smarter then 50% of the people and it's a constantly contested fact.
