Gear ratios, Shift rpms, and Speeds (archive)

I was looking in the archive and found this info. I just wanted to ask did people agree this info was pretty close or have there been updates since? Info was posted by Bob //M3.

final drive ratio: 3.64
1st 4.32
2nd 2.53
3rd 1.67
4th 1.23
5th 1.0
6th 0.83 => overdrive!
rev 3.75

Based on shifting at 8,000 RPMs, these are the RPMs the engine will be at "after" shifting from the previous gear to the next higher gear:
2nd from 1st: 4,785 RPMs
3rd from 2nd: 5,281 RPMs
4th from 3rd: 5,892 RPMs
5th from 4th: 6,504 RPMs
6th from 5th: 6,640 RPMs

Okay, at "8,000 RPMs", transmission gearing 1st thru 6th @ 4.23, 2.53, 1.67, 1.23, 1.00 & 0.83 and final drive gear of 3:64 to 1, these are the speeds in mph:
1st gear - 40.25 mph
2nd gear - 67.30 mph
3rd gear - 101.95 mph
4th gear - 138.43 mph
5th gear - 170.26 mph
6th gear - 205.14 mph
