I double clutch on downshifts, and I also like going down to each gear for timing. Skipping just feels strange to me. Let me share something I teach my students learning heel toe and proper downshifting called the rule of halves. I'll suggest Road Atlanta 10a for example. 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.

The .2 RS has a shorter final drive ratio. 5th gear comes up on most tracks where a non RS from 996 GT3 and up have pretty tall gears thus very rarely requiring 5th gear. At least with most drivers like us. I know guys getting into 5th with tall gears in places I can only dream of. Most of them are paid real money to drive cars fast.
