Regarding the estimate of the "Maximum recommended average current draw to prevent pack damage" - the max current is the square root of (6*capacity/IR)
The calculation of the FOM/Current draw were developed by Mark Forsyth and Wayne Giles. As always we emphasise that this is just a pragmatic rule of thumb based on extensive practical battery testing that seems to reflect practice fairly well over a wide range of LiPos and capacities - although some recent cells like the Turnigy Graphines do better than predicted. It has some theoretical basis in a maximum allowable % of energy dissipated internally (6 Watts/AmpHr) but we don't rely on a theoretical explanation. It is a purely empirical observation that has been surprisingly useful to date.
