I just divided the damage by 1400, the damage per second a typical gank Talos puts out.
It isn’t perfect as the Talos has a 4+ second rate-of-fire which will introduce some significant error depending on where in the firing cycle each ganker was when the Rhea exploded, but it should be a good enough estimate over that many samples and you can see that the clicks are distributed rather uniformly, not clustered around a single time (or perhaps two) as you would expect with input broadcasting.
