This sort of the decision is best approached by knowing a reference position. Here's one that I got from MCG's Gammon Village article. It's a 0.93 take.

The diagram below is also from MCG's article. Now it's a borderline redouble.

In your position, I think White is a bit better off than in the above borderline redouble position. Though it's often better to be closed out in this kind of priming battle because then you won't collapse your prime, she has those valuable extra pips of timing in the outfield. Of course those checkers could get sent back if White is unlucky enough, but overall I think White benefits. So, no redouble for me, although it could be close. Blue does have a couple of extra pips of timing in his home board, and although that may not seem like much, small pip counts can make a big difference in prime-vs-prime positions.
