Angle - Blinkers Off

[miraja2]

Question: How much does their recent running style factor in?
I personally don't use "blinkers-off" as an angle (although apparently I should) but for Jim and others that do use it, I assume that if a horse was rank - or simply wouldn't rate - in his recent starts with blinkers, you look at the blinkers-off angle as more meaningful. Is that true?
If a horse shows no early run with blinkers, do you still think that taking the blinkers off will sometimes help?
