GPU to 72 status...

[TheMawn]

I tried four 74 to 75 with already known factors and all four were successful so I'm now quite confident that this boils down to bad luck. Thanks again.

I'm afraid it makes the table rather wide, but I know people have been wanting this data exposed.

It's all cool! Thanks, Chris.

Thanks for double checking.

Only a few years ago economic policy was (wrongly) set because of a simple mistake in an Excel spreadsheet....

And then there's a telescope mis-ground, missions (including commercial flights) failing based on confusion between metric and English systems, and wah dee doo dah.

Not so much. It had more to do with that mirror (and the smaller mirrors) and instruments being out of whack with each other because the company that delivered the mirrors was used to delivering spy satellites that the telescope was derived from. The same grinding program was used for it as the sat's.

Years ago when I mentioned it and the fact the shuttle's cargo bay was design to fit a KH sat, to a friend that had a high level security clearance and had done early work on the STS, they were surprised that I knew about the KH sats. I talked to them again recently and mentioned that the Hexagon (KH-9) program was declassified, this surprised them again.

My understanding (very likely wrong; no "insider" knowledge) is that a planned test on the ground which would have cost ~$1M was skipped for budgetary reasons.

In case you want a few more:

This morning the Workers' Overall Progress report is showing I have done 2 TF >75. I don't recall doing anything this far; it would be an 8-hour job.

Rats; I forgot about my little fling with the 332M exponents. Sorry about the false alarm.

No problem. Trivial query.
