Useful, and not so useful. No distinction given to spawn positions which affects these timings - and you have to be wary of this before assuming you hit a position before the opposition. Standout areas this could be problematic are Mirage CT rushing ramp, Inferno mid and banana, Overpass to fountain, Train A main - those timings differ substantially on spawn location.
Missing some vital timings as well - Overpass could do with a monster timing for CT vs the T's, and why on earth would you have the timing to rush top connector as T? You're never rushing that, you want the timing for CT vs T to meet in connector. Why does the Mirage CT timings at B stop at market? The important timing is vs a B rush..
Obv impossible to put all the timings in there, but a lot of the timings here are borderline useless.
Not withstanding, there's still plenty useful things to glean from this guys work, and I applaud the effort.
