Nick, I'm sad to inform you that Udo died a few years ago after a lengthy illness.



That is sad.

In the Johnson article he works very hard to get to published L/D. However what struck me is how far off the manual's numbers are at the high end and he doesn't mention it.

Are many manufactures too optimistic at the fast end?


No Nick, those polars are gospel to the manufacturers, they wouldn't fake'em! In case you are wondering, there's absolutely not gambling going on at Rick's Cafe, either.
