Testing subtracting 32 on the low end of pip count range

In Response To: Very nice, but just a tad conservative for raw pip counts (neilkaz)

Subtracting 32 rather than 33 looks good here since (53-32)x2=42 whose sqrt is closer to 6 while (54-32)x2=44 which has a sqrt closer to 7. (Note that I tested more than one 54-61 pip efficient position and all were clear takes)
