If Maria withdraws, the spot doesn't have to be filled with another russian skater, so Sima might not benefit from that. Let her skate if she wants to. I for one am glad to see her not giving up.
I know it isnt guaranteed that Stotskovas spot would be filled by a russian since the frensh fed decides but if she where to withdraw in good time I would say there is like a 90% chance it would go to Sima and 9% chance Gubanova and 1% to a skater from another fed. In the last couple of years a withdrawal from a major fed has allways been replaced by someone from the same fed and then first by giving a second spot to someone who originaly only had one.
Im not saying Sotskova should retire if she wants to skate but I could see the sens in withdrawing from GP if she isnt in competetive form to give someone else the chance.

it's like WC happened and I missed it!
