Prelim. results!

Here's the results so far from 22 positive posts:

5.13 : 1
4.88 : 1 "Hey, that's me!"
4.56 : 3
4.10 : 6
3.73 : 3
3.55 : 2
3:50 : 1 Furd
3.07 : 5

So, out of 22, 11 (DEAD EVEN!) have pretty steep gears! Average of 4.39. Good job! The other ten have an average of 3.34 with their 3 series carriers.

Who will break the tie????

Come on someone, give us another 4.56 to tip the scales for us tire roasters!
