Soviet tests of a FW-190A-4 did show about 19 seconds in turn times, but it was displayed as 19-23 seconds, implying the difference in side of the turn(?).

Nope 19-23 seconds means exactly what any engineer/test pilot would expect it to mean - somewhere between the upper and lower limit, but not accurately measured. Or if it doesn't, it is down to you to provide evidence why, not just assume it means what you want it to.
And as for 'catching the stall's wing drop' with aileron, this is nonsense if you are talking about a sustained turn (along with airspeed, turn rate and altitude, AoA must be constant so either the wing is stalled or it isn't), and dubious as a means to recover from a stall anyway. If a wing is stalled, down aileron is going to make it worse.
Even with the luxury of an autopilot, and no worries about structural/engine failure, fatigue from G forces, instrumentation errors and the rest, practical experience with the few tests I've run tells me that any measurements of turn rates need to be taken with some scepticism. Out of curiosity, does anyone actually know how turn rate was measured? The compass would be useless, and I'm not sure a gyro would be much better - they tended to tumble with extreme manouvering.
