Player rating for tournaments across all installments of Heroes.

Very positive. But then, a general ranking should definitely be held for those who have played 3/5 of the total number of tournaments. Otherwise, with the addition of N/2, the winner of a tournament with 30-40 participants will easily outperform those who have participated in 3-4 tournaments with fewer than 10 participants. Or, instead of counting from the last place, we could count from, for example, 15-20, creating a single point balance for all tournaments (this would also give participants in less prestigious tournaments who finished in last place more points than those who played in large tournaments but didn't make it to the top. This would increase attendance!).
