DealCalculator (or use to estimate EV or finish probability)
 

I made a Palm application to calculate reasonable deal splits:

Any questions or comments welcome,

PS: Note:
Not guaranteed bug free.
Uses the independent chip model, which slightly favors small stacks, but is MUCH better than the McEvoy model. Perhaps sometime I will also include the better random walk model. Errors are typically <~1%.
Only does up to 8 players (each additional player increases time by about x5, so full tables are not really Palm compatible (my laptop is fine for up to ~18)).
Uses integers for much of the data, so add zeros on the end of Prize$ numbers if you desire more significant figures in EV.
