Yup - I liked Barbarische's idea but it omitted the "bad things round up" rule. [well, almost: points up, feats and combat results down]
For Very Fit 1 or 2 FP = 1; 3 or 4 FP = 2. Faster recovery means being back at full fitness inside 1 hour instead of 2.

Uses per turn, for someone without extra attacks:
1 FP for Defence, 2 for Attacks (either 2 Rapid Strikes at -3 with normal damage or 2 Rapid Strikes at -6 with +2 damage).
NB All Out Attack would allow 2xRapid Strike and 1xMighty Blow, but that's still only 3FP per turn.

Extra Attack for a "normal" human can only be used for either Feint or just straight-up attack; I'd assume Mighty Blows was okay for this attack but you're allowed only one set of Rapid Strike. I wasn't sure about using All-Out-Attack but it's all covered on page B54.
Not certain of this bit but it's logical: both attacks must either be All-Out or you can't use All-Out, i.e. you can't have one normal and one All-Out.
