I had an idea a while ago that half turns should count as 1.5 turns for the purposes of simple counting, since half moves take roughly longer than a single move and less than two distinct moves.

Actually I noticed in J Perm's alg formula, he suggests the same exact thing, albeit with other things that are much harder to tell from just looking at an alg like hard regrips and overworking fingers. In @trangium's Movecount Coefficient Calculator the number is slightly higher at 1.65.

Now here is an application. For A perm R2 B2 R F R' B2 R F' R, it's 9 HTM or 12 QTM, but I think the value should be in between.

Another case: For F2L 32, the triple sexy (or inverse sexy) case, that alg is 12 or 11 moves, compared to 7 HTM or 12 QTM moves of R2 sune: R2' U R2 U R2' U2' R2. However I think the movecount of the R2 sune should be counted in between with 1.5TM as 9.5 moves. (This is a bad example because common 4 move triggers like sexy or inverse sexy are so fast they should be maybe counted as 3 or even fewer moves, and the R2 sune has a special execution with alternating R2 that's like the pi OLL.)

To emphasize, this is not useful for counting moves for FMC, but as a little bit more accurate way to quickly and roughly tell how fast an alg is to execute compared to HTM and QTM, without counting things like how R/U moves are easier and regrips and risk etc.
