This is something I've been using for a while, and I haven't seen it anywhere else, so here it is:

When someone posts a BLD time with a scramble, I don't always want to do the scramble to see how easy the scramble was.

How easy a BLD scramble is is very objective however, and really only depends on the number of corner targets, the number of edge targets and the number of flipped/twisted pieces.

I propose that people start posting with their times/scrambles something that looks like this:

(# of corner targets)[SUP](One apostrophe for evey twisted corner)[/SUP]/(# of edge targets)[SUP](One apostrophe for evey flipped edge)[/SUP]

So for example, this scramble:

L2 U2 L2 F2 D2 F2 D2 U B2 U F2 R' U2 B U R2 F R2 D F R'

For me would be accompanied by the notation 7'/12 (edges are even # because of how I do parity)

Note that this would not be the same for everyone, but if people scramble in their solving orientation, it should be quite similar.

Now when I tell you that my time was 34.40[10.59] on that scramble, you know approximately how good my execution was.

This leads me to two statistics that accompany this notation quite nicely:

For this scramble, I had 11 algs: 6 edge cycles, 3 corner cycles, parity and one corner twisting alg.

My TPA would then be (34.40 - 10.59)/11 = (23.81)/11 = 2.16 seconds/alg

For BLD, this is a much better way to rate someone's execution than TPS in my opinion, since BLD is about your transitions from one alg to the next more than it is about how fast you can turn.

For that scramble my TPT was 10.59/20 = 0.53 seconds per target. The denominator is 20 because I had 7 corner targets, 12 edge targets and one twisted corner.

I think TPT is a better way to look at memo than simply looking at the memorization speed, because not all scrambles are the same. Even though this solve had slower memo than the 26.70 I got here, I count it as a better memo since there were many more targets and the TPT is much lower.

Anyway, I hope these statistics help people relate times to scrambles better, and help explain why a lot of BLDers have negative reactions to fast solves and positive reactions to slow solves.

**TPA**= Time Per Alg = (execution time)/(# of algs)For this scramble, I had 11 algs: 6 edge cycles, 3 corner cycles, parity and one corner twisting alg.

My TPA would then be (34.40 - 10.59)/11 = (23.81)/11 = 2.16 seconds/alg

**TPT**= Time Per Target = (Memo time)/(Number of targets + Number of twisted and flipped pieces)For that scramble my TPT was 10.59/20 = 0.53 seconds per target. The denominator is 20 because I had 7 corner targets, 12 edge targets and one twisted corner.
