Even if we took the idea of ACT being unreliable at face value, we have nothing else to go by except his word. Once again, no one will care what Yoshida claims without hard evidence they can prompt scrutinized.
For solo numbers ACT/fflogs are 99.X% accurate, but for party contributions they're not as perfect because battle logs don't record dot damage and the server only sends a combined tick in the data packet, so it's impossible to tell the exact damage each dot did or whose it was, what crit/dh and what didn't. We also know from pvp that SE does have their own damage calculation system, so it's fair to assume that they have the more complete data.

It's questionable if they know how all the possible party setups interact with each other though, as there's some evidence pointing towards physical ranged classes being possibly underestimated (SSS dummy numbers). It's also possible that the numbers are skewed on purpose because of some undisclosed design philosophy. We just really don't know.
