What Time Format Gives Best Measure of Chess Ability?

Daily is too inhomogeneous: one may analyse for 12+ hours, another for 12 seconds.
I vote for classical 90|30, followed by rapid 15|10.

I conclude Blitz, 5min times do not fully show a chess players true abilities you have to include Classical play controls to show a person's ability especially in middle game situations, I personally prefere playing between 1-3 days per move, lot of my opponents play very quickly and lose positional advantages they had, lose games they should have drawn or worse, its as though they are still in blitz mode too much play at quicker controls does not improve one's understanding of chess and areas one needs to make improvements this is where a degree if classical play shows its benefits!!
