Of late:
Articuno (raid day) 7/8
Zapdos (raid day) 12/13
Regice 10/10
Registeel 2/2 (first one perfect)
Regirock 3/4
Ho-Oh 2/2 this wave so far, 15/17 overall (and one of the 'escapes' was that the game glitched and we timed out of the raid after winning).
So I think I'm hitting them pretty well, totals of 36/39 lately.
