Yeah, that's how I remember it too!
I think calling it anyone's anything will limit the number of entries, unless it just becomes "The Metronome Race Thread", or somesuch. Many will ignore a thread called "Relentless like MarcelP", through not being relentless enough!
@Mark, following your request for rule amendments:
I think there should be set time brackets, like in the 'race to' threads. In other words, rather than just 'divide 4000 by Ao100', I think there should be some rounding involved, i.e. have 'race to 180bpm'; 'race to 150bpm', 'race to 120bpm'. Participant takes 4000/Ao100(or 50), and rounds down to nearest race bracket.
For example, my Ao100 is normally around 25 seconds, so I get 160bpm. If I set a metronome to this, I know for sure I will DNF 75% of my solves, as I've never done any metronome practice. If I round down to 150bpm, I will probably DNF a few at first, but after a few weeks, maybe 'graduate' from this to the 'Race to 180bpm'.
I think intervals of 30bpm would be sufficient, starting at maybe 60? Based on an average of 60 turns for a relatively efficient CFOP solve, this would mean:
Race to 60 BPM ~ 60s averages ~ 1tps
Race to 90 BPM ~ 40s averages ~ 1.5tps
Race to 120 BPM ~ 30s averages = 2tps
Race to 150 BPM ~ 24s averages = 2.5tps
Race to 180 BPM ~ 20s averages = 3tps
Race to 210 BPM ~ 17s averages = 3.5tps
Race to 240 BPM ~ 15s averages = 4tps
etc. This means big jumps at first, but I don't think lookahead should really be a concern till at least ~40s, as if you're significantly sup-40 and know your f2l cases well, there's something wrong. If there was popular demand for it, no reason why other brackets, like 75bpm, couldn't be added.
This would also make running the thread easier, as you wouldn't be looking at graduates from obscure numbers, like the race to 157 bpm race, people would be lumped together. Just with the time race threads, obtaining 3 passes in a row = graduation and optional participation in the next race.
I like the scoring system, I think that will work well. Following on from my points above, although the races would be separate, you could still graph scores across all races based on lookahead score.
I'll be doing my entry tonight, if I have time. Might even film it as well - if it's not too horrendous then I'll put it on yt.
