Okay so I don't think this warranted its own thread yet, so I thought I'd put it here.
I noticed that there is no formal way for clock solvers to communicate details of their solutions. To solve this problem, I suggest a standard which would serve a purpose similar to the metrics used in other puzzle reconstructions (HTM, STM, Noah metrics), which could serve as a way in which a solve can be analysed. I would consider the following two numbers to be most important to a clock solve:
1) What I will provisionally call the 'Cog Turn Metric', or CTM, which will be the sum of the absolute distances travelled during each move. So a turn from 12 to 7 and a turn from 3 to 8 are both 5 CTM in length.
2) The number of pin adjustments (PA herein) made during the solve. 1 PA would be defined as any change to the pin order which is then followed by one or more gear turns. So this includes any pin adjustment at the start of the solve, but does not include skipped clocks (where an initial pin adjustment may be made out of false judgement).
I feel these numbers together give a good indication of the difficulty level of a solve. From these numbers, we can define two obvious statistics: the CTPS, which is the CTM divided by the solve time, and 'moves per second', which is the PA divided by the solve time.
If this does not make sense to you immediately, I will include a couple of reconstructed solves, along with their statistics, so you can see how the idea works.
I may do another Ao12 with reconstructions at some point, and if I do I will incorporate these statistics into my reconstructions.
Does something like this exist already? I know clock reconstructions are super-thin on the ground, so there's not much opportunity to use it, but I thought it was a fairly nice statistic. What do you think?
