Would both the LMT 1940 and 1950 be considered XL size? Or is the 1940 more L size and the 1950 XL size?

Argg! LMT has too many sizes! Better question:
Where do the following motors fall in the S, L, XL (and maybe XXL) size rating?
1920 S?
1930 L?
1940 XL?
1950 XXL?

I have come to a size comparsion. The 1920 is or has the same size rotor as a s can 540.
The L can is 35 x 19 mm rotor.
The xl can is a 50 x 19 mm rotor.
So the 1950 would or should be and xl. IMO
The 1930 and 1940 is another question.

Added Mugen diff and temperature converter (sorry I forgot about the diff Dafni).

CHC: So, you think a 1950 has the same torque as an XL motor of the same kv? I figured an XL was closer to a 1940. What I ended up doing is made a list of 4 motor sizes (S, L, XL, and XXL) for each motor can size (eg: 540) and equated each level with a vehicle weight range. Then, each motor falls into one of these levels so the program knows which motor(s) to choose based on weight. It seems to be pretty accurate judging by the common setups found here.
