Some would disagree with that.
According to the Hungarian training calculator it would take my player Nick exactly 2.00 weeks to pop in pressure with a level 6 trainer which I have. If I only had a level 5 it would take him 2.04 weeks. If I only had a level 4 it would take him 2.12 weeks, at level 3 2.21. Two pops a season is about a 20% improvement. This suggests that the actual difference is about 1/10 of that, a 2% difference. So that would translate to more like 1 pop every 5 seasons. I am not saying that they are right or wrong, but a lot of people quote this "two pops a season" as a fact and I think it is much more an opinion and probably closer to an urban myth.

By the way I am not training him, I just used him as an example because of the randomly round number he had.
