isn't the rule basically that the claimant (white) has to prove that his opponent has "no practical winning chances" , and that for a claim to stand the claimant :
1. should be materially superior ( a rook up was mentioned before )
and/or
2. has to demonstrate that the opponent cannot win by normal means
and/or
3. demonstrates his opponent has Insufficient means to win practically
and/or
4. claims his opponent has insufficient mating material
The onus is on the claimant to demonstrate the draw and time shouldn't be a factor unless the opponent has either insufficient skills or time to complete the game.
