I will also note that hogdons pressures they noted with that load were a touch below 32k psi.
saami max for the 40 sw is 35k.
Right.
You should not read load data with the pressure for the max load falling significantly under SAAMI max to mean that you have a cushion. You should read it to mean that .1gr more powder took it over SAAMI max, and that
Wow, pressure is really climbing fast at the top of the charge window. 
.40 S&W is known for dramatic pressure spikes with modest changes when running near or at max loads. If this were 9mm, I'd say "Meh, he's probably in +P range, no big deal." But with .40, there's no +P. It's a much shorter trip from SAAMI max to a catastrophic failure with .40S&W.
