All you need is that site and a similar one that provides crater characteristics for weapons effects (I have a cool circularcslide rule from Glasstone's book)and find those parameters e.g. yield, asteroid size,that result in the same general effects. You can then plot them against each other. I bet it's close to a linear regression.

They don't have the data that you suggest, its just an OK site, and no free Asteroid Calculator download, so that is weak.

Its a broad range considering the assumptions that have to be made. Density has to be assumed, diameter is sometimes a pretty broad guess. So the frictional losses are pretty minor in relation to the other uncertainties. Much of the friction will result in heating of the 'roid anyway, so that energy is "conserved". You would also have to consider angle of incidence and that would be a crap shoot.

See once again, you over-complicate where there is no benefit, kind of like your method of boiling water.

Then compare the crater size from the asteroid to the same size for a comparable h bomb.

Much more accurate. Do the job. But do it accurately. Accuracy matters when you are,seeking validation.

Your calculator is off because it doesn't account for friction losses when the asteroid hits the atmosphere. What did you say your degree was? Also, if the asteroid hits water vs land it would have a different effectime and magnitude. It's simple.
