I think that depends on your number of daihatsu and drums you carry. If it will empty the bar then it's considered to switch to the final form.

If still not too sure, take note of the TP points you decrease every sortie and the number of sorties needed, then remove some drums if neccesary until you get the smaller number possible. Unless you are well prepared, the most you'll get on hard will be A ranks.
