Guys on BBV say I suck

Can somebody please explain the "Turn CBet%" and "River CBet%"? Are these dependent on earlier streets, i.e. did he CBet 94.4% of the hands on the turn he already CBet on the flop or did he CBet 94.4% of all hands he was still in by the turn. The latter seems to be nearly impossible, but I just wanted to make sure.

And in general, shouldn't the CBet% get lower on each street and not the other way round?
