Yep. The 5th gear test is the most common test to see if your clutch is slipping. You really want to do it at torque peak, so you could do it at 40 mph if you want.

Our cars essentially make peak torque from 2400-3200 RPM (before the torque dip), so you could test it in 5th in that RPM range. If my math is right, that would mean flooring it from 40-55 mph in 5th, basically what King Tut said.

You may be over thinking your one time clutch burn accident. If you do it all the time thats bad but if it's just a few times in the lifetime of that clutch, you should be fine. Sounds broken in now.

We just did the fifth gear test recently in my husbands tc. in a safe empty lot with no one to get hurt around you, put it in gear (higest gear you have) and take off from a stop in that gear. It's supposed to stall. If it doesn't stall and you can move it's the clutch.
His car didn't stall, it acted as though we were taking off in second. We just had the clutch replaced and this is what it looked like.

this clutch had 110,000 miles on it. so even if you think you did a little something to it...it will still last a long time

Jake I'm sure you clutch is fine from what you tell us. It should have lots of life left. Just drive it normal and no need for extra babying

I did something similar a few times with my E36 bimmer and the clutch made it to 110K. When the clutch needs replacement, you will know for sure when the clutch slippage will become obvious during launch and when you need to pull under stronger loads.
