Papa,
I see Tencendur as a horse that's had a lot of stuff thrown at him in his career. 5 straight routes, 4 different jockeys, now blinkers for two straight, moving from inner surface to regular surface, 3 off track races. Since they added the hood he works quicker in 4 of the 5 workouts.
Eventually they may find this horses' comfort zone and then see where he goes from there.
Maybe the horse hasn't even been able to concentrate on just running with all the changes that occur.
I can see using him myself somewhere on a couple tickets. Wouldn't be the first time many of us used a horse that could get lost on the odds board.
Good luck and keep on swinging (horse race type swinging, of course).
