Thanx Dunk,
It certainly seems that way, I have captured under 10ms with over 100fps looking back at vids from month ago, infact I knew these fast frame rates seemed to be the go, but the vid data only showing 30% Gain, with a similar 30% histo
I will definitely crank up the Gain in future, & like yourself & Paul H mentioned, look for a 70+% Histo,

BTW: Just reading through 'cloudynights forum' concerning frame rates & bit depth, 10, 12, 14 etc, some interesting findings there ?
All the best !
