Interesting observation. I concur with you more or less except that I'm somewhat reluctant to agree that Momota played better at the Thomas Cup and World Championship in 2018. Personally, I just feel that in 2018, not long after he came back from a one-year suspension, most of the players, the more so his peers and those younger found him a novelty, were unfamiliar with his game and were often subjected to the element of surprise. Also it should be pointed out that in the WC'18, there was an unusually high number of late withdrawals, some of whom were considered serious contenders, such as LCW and Son Wan Ho, just to name two. As a result, the draw became skewed with the half opposite to Momota's more heavily weighted in strength. That's not to take away anything from Momota's triumph, just to put it into perspective. No doubt about it, Momota is still widely regarded as the current world number one, very much the player to beat for every player. However, now that the OG qualification cycle has begun, we would be well-advised to expect the unexpected.
