ErrorCheck=1 won't hurt. I think the polymult library is good at keeping roundoff error well below 0.5. However, I've not thoroughly studied the matter.

A few bugs were hopefully fixed. Stage 2 % complete should now start at 0% and proceed to 100%. If you're happy with build 7, there is no reason to upgrade.

One issue is that 30.8 has "broken" the GHzD formula. That is, 30.8's huge B2 values means GHzD does no longer correlates with time spent on exponent.
