Thanks Joe,

I do "do the math", or at least very rough math, to compensate for the
restrictions imposed by only having 25% or 34% options. I thought Terry's
statement that he uses the Sanderson method meant that he was using a SAT
and that maybe his SAT was capable of calculating different percentages
than my SAT3... he's since clarified that. (Thanks, Terry!)

I've never attempted a blind overpull, and don't plan to any time in the
foreseeable future. Even after (only) 8 years at this I don't feel
comfortable enough to try it.
