Comparing deferent side cuts based on waist width

[Chris Downing]

I have been experimenting with side cuts and trying to get it right. So I came up with a simple formula for direct comparison in how much a ski will pull you into a turn or push you out of a turn no mater how wide the waist is.
For instants my latest DD is 140-99-121 (tip-waist-tail) Subtract the tip from the waist to represent how many mm bigger than the waist. 41mm of pull into the turn. Second subtract the tail from the waist. 22mm of push out of the turn.
140-99=41
121-99=22
The ski is a 41-22
At 180 cm. the length is always the ?
To compare my favorite skis!
The Stockli GS 105-66-88 is a 39-22
The Stockli SL 116-63-100 is a 53-37
The Stockli Scott Schmidt 122-89-112 is a 33-23
The Stockli DP 125-94-111 is a 31-17

Tell me what you think I am always trying to learn something new about skiing.
