Hi list,
How is this calculated and how do we know the 90% to 95% loss
calculation is accurate without knowing the mass of the asteroid before
entry and after recovery of every piece that lands on the surface of our
planet?
Has there ever been such a case?

I think that you can usually figure that 95-99% of the mass of parent
meteoroid is lost. That seems pretty consistent with the estimated
mass of observed fireballs compared with the mass of recovered
meteorites.
Obviously, what is typical is pretty loosely defined; I don't doubt
that there are exceptions to the rule.

Subject: [meteorite-list] How much survives entry?
Does anyone have a rough estimate on how much material, say ordinary
chondrite, is lost during entry? 80% converted to light, heat and
dust? 90%? 99.9%?
