In reply to Chris the Tall:
The rule says
"An attempt on a boulder shall be considered successful when the Boulder Judge has announced “OK”, having determined that the competitor has either:
a) Controlled the marked finishing hold of the Boulder with both hands"
It does not mention anything about beeps etc or if the timer shows zero. Different timers have different characteristics eg the one from Vail is set up so that if you hear the last long beep starting then the time is over (ironically this timer is from Iran but don't tell Trump that I brought it in!).
I don't know which timer was used in Mumbai as I wasn't there.
As for the timer on the stream. If the timer is an old skool LED system then there is usually no HDMI output so the clock on screen is a feed from a camera filming the timer. In Mumbai it looked as it was connected as it wasn't LED and it didn't shake.
The 'in control' bit is important. On men's P1 in the final you could easily argue that you weren't in control until you had stopped the swing - there was an incident like this at a BWC in Swiss years ago - last move was a sideways dyno, one athlete clearly had both hands on the finishing hold but was only at the start of the swing when time ran out (it was semi final so fixed clock) so they weren't given TOP.
For Shauna you could easily argue that she was in control as soon as her second hand was on the hold. But was she in time, well not my decision
