So you are shooting in manual not eTTL then?
Oh I have tried both ettl and manual mode, same story. These examples were in M mode to illustrate how the power output changes at random , even though I don't change it.
I've tried with and without the AC3 , and also used a TT5 as a transmitter to another TT5. Same story, with loads of random errors.
I often need fast speeds for portraits so I need them to work at all speeds-
