Thank you Visigodo, is true that exist sub types of Valdaic type. On ukrainian
map are basic two: a) Valdaic (I think classic in Belarus and north western Russia, northern Ukraine, Poland, Northern Slovakia.)
b) Lithuanian variant of Valdaic type

And on russian graph, which i will send (but i think you will know this graph),
are 3 variants of first Valdaic: 1) Lovat-Sorotsk - CI=82,8
2) Valdaic - CI= 83,O
3) Valdaic - CI= 83,O but smaller FI than
second
