Player rating for tournaments across all installments of Heroes.

Equate 5 stages of a blitz to one. Regarding the perceived simplicity of the Tournament – this is speculation, and announcing the results of the first stage, along with a description of the winner's Walkthrough, will dispel these notions. Furthermore, the rating will make the Tournament competition more intense – it will provide some motivation, however small.
P.S. I specifically expressed my opinion on this matter before the results are announced so that some people don't think I'm "looking out" for myself. And the announcement of the results will answer this question.

It's not about the simplicity, but rather that players spend less time on it anyway. And if they come up with even more rating-based Tournaments. In my opinion, it would be logical to calculate the rating based on five rounds of a single blitz once, at the end of this blitz Tournament. And throughout the blitz, there would be a competition to see who gets rating 100 at the end, and who gets a little less. To determine the overall winner of the blitz, points will be awarded for each stage to each participant in each round. Personally, I simply won't be able to update and calculate the rating so often.
