Talpa has obviously riled you enough to cause you to re-set your reality into a different base than 10
If, in hypothetical land, Stoner had not been taken out by Rossi, and then Stoner had gone on to win the race he'd have had 25 more points than he ended up with in Jerez. That is the maximum he could have lost due to Rossi, mathematically as far as I can see.
I assume that the extra 5 points you are claiming come from expecting that Lorenzo would have finished second and only gained 20 points. Why not go the whole hog and surmise that if Rossi had taken out Lorenzo then Stoner would be 50 points ahead and therefore Rossi cost him 50 points by torpedoing him and not Lorenzo??
Also, as this is hypothetical land, maybe someone else would have torpedoed Stoner later in the race, maybe he would have made a mistake and crashed (lots did) and he'd still have ended up with nil points, or maybe he'd have finished and not won. 25 points is the max haul from a weekend and that's all anyone can claim to have been lost due to Rossi's error.
I would also take you to task regarding catching Lorenzo. He has a 20 point gap to Lorenzo (45 points versus 25) and that would mean him winning 4 races in order to catch Lorenzo assuming Lorenzo finishes second in those four races.
Personally, I think he will win the title this year regardless of the current points standing.
But I have been known to be wrong
If stoner wins and lorenzo finishes second he has 50 points and lorenzo has 40, as opposed to 25 against 45 now, which is 30 points net difference, but perhaps I was unclear that I was referring to him retrieving this (potential) position rather than lorenzo's current lead. I don't think him winning is all that presumptuous either seeing he was fastest in the warm-up by some margin, ahead of lorenzo who won, and very far ahead of the eventually second-placed pedrosa on the same bike and tyres at the time of the incident; both riders who were ahead of him at that time, momentarily in the case of the second rider, crashed of their own volition, and he appeared to be riding so as not to crash like them. This was also a race in which he possibly had a bike advantage against lorenzo (and rossi for that matter) which he may not have later in the year.
FWIW I am specifically annoyed with talpa, not other rossi fans or even rossi himself. Regard me as intolerant if you like; you are correct that snide remarks about stoner's "luck" / defeat in mind games/need for excuses/need to cope with adversary (presumably meaning adversity) in this context did rile me, but not to the extent of being arithmetically challenged
