Player rating for tournaments across all installments of Heroes.

Just look at the average rating values (using the old system) to understand that 50 is too high for a beginner (the probability that this is a strong player who came from another portal, for example, is extremely low; most likely, this is indeed a beginner, and their result will be average). Setting it to zero is certainly not the right approach, but a number greater than 30, in my opinion, should not even be considered. And don't forget that for strong players, the difference in average rating will not be significant, and by introducing a large constant component to the contribution, we will significantly diminish the role of strong, consistent players.
