On the January 9th page, you posted your final drivetrain speed. When I run those calculations through the JVN calculator I only get 100% efficient speeds of 18.92 ft/sec and 6.81 ft/sec, whereas the blog posting shows 19.8 ft/sec and 7.1 ft/sec.

What would explain the difference?

I used CIMs at 5310 rpm free speed and the gearing showed on the blog posting.

Thanks.
