That's why it may look less flashy than her very best matches in 2020/21
Well, if we only remember her very best matches, and forget the average matches or, especially, the losses, then the analysis is distorted. I find what happened in 2020/21 less flashy. Losing in the round of 16 or before in the majority of tournaments of 2020/21 was not flashy at all.
it is more reliable and doesn't require her to play at 100%.
I think you said it well. In 2022 Iga has realized that she doesn't need to play risky, or go all-in, to win against the best players. Playing risky or all-in meant she didn't always have control over the situation. This year with Wiktorowski, just by playing her normal level, she is able to win against everybody and have control over the matches.
It's true, perhaps, that Iga in Roland Garros 2022 didn't look as convincing as in other tournaments. She had some shaky moments. Perhaps, it was the pressure to win her second grand slam. The best thing, and the
scariest for her opponents, is that she won the tournament anyway! In any case, I think she has had many brilliant matches and tournaments this year. She has won 35 matches in a row! That says it all. IMO, her consistency and playing her normal level (because her standard is so good that she doesn't need to play risky to win) have been some of the keys.
