A few years back another board member sent me some Ford calibrations with cranking pulsewidth given as a function of engine coolant temperature. I plotted the data on a log scale for PW and both engines turned out to be linear, so from that I gather that cranking PW has exponential decay.
Try this in the standard MS-II cranking pulsewidth table and you'll see the shape of the curve that is appropriate. If you have a good hot cranking number, try scaling the numbers (minus open/close time) that I give below and see if that works for you.
