๐ I created this chart back in 2011, using touchdown splits from the PB races of top athletes in both the 60m & 110m hurdles.
It was a model built entirely on real-world data. Incidentally 7.32 = 12.75
JaโKobe Tharpโs 5th hurdle touchdown are indeed very close (~6.48-6.50)
Touch down at H5 was very similar for his 7.32 60m hurdles indoor. People donโt realise that the WR should already be 12.7 or faster if Aries could have stayed healthy in 2013 or Grant managed to adapt step length for the last 4 hurdle units.
