If you get all heads or all tails then use the last toss as part of your next set of 3.

E.g. HHHHT -> HHT -> 6

Ah yeah of course, there is a zero case as well. I was thinking you just restart as to not bias the result. That's an interesting alternative though

That will make HHH always 6 and TTT always 1

		HHH becomes H Then depending on the next 2 throws HH -> keep going HT -> 6 TH -> 5 TT -> 4 For TTT similar with K,1,2,3
