If you begin your braking at 200' in 5th gear, set up your 4th gear downshift at 100' marker (halfway), then time your 3rd gear downshift at 50' (halfway from your last downshift to turn in), and again 2nd at 25'. Since your rate of speed is decreasing, you have adequate time to make these shifts at the proper revs without a risk of over rev letting the clutch out with each shift. This works consistently in threshold braking situations with multiple downshifts.
I really like this idea. Will try it out for sure. Thanks for the tip.

Ahh, that makes sense!!!

Nice plan.

I hate that wall. And I have seen it reach out and grab a car.
