Sorry for the cross-post, but does anyone know if Lending Club uses the same 30-day calculation?

I've been trying to figure that out but it's proving to be a bit of a challenge.

My current best guess is they use 30/360, but the numbers only really work for higher value notes, i.e. $500 or $1000 notes. $25 or $100 notes can be off by quite a bit.
