Yes, you are right. It's normal for Remco to improve from the past seasons. He is still young, he had that terrible crash in 2020, he finished a GT for the first time in his career last year, so his best ever start of the season should have been expected. And I think we should all agree that Remco has never been as good in March as he has been this season. He'll probably be even better in May.Hmm very dubious claim giving the timeline of Remco and what WT he participated in. (or i"m reading more into it than you intended).
Joined in 2019 at 19year old.
Started the season 2020 with 2 victories early season (no WT since covid hit.) cycling started again in august --> (won WT stage race), then the crash happened.
in 2021 he didn't have an early season.
in 2022 his early season (e.g before LBL win.). he partipated in only 2 WT stage races. Tirreno didn't go well (11th but was very active and tried) Itulzia he was 4th (3minutes ahead of Roglic)
2023 is now.
So just want to point out that the lack of data doesn't mean its 'bad'. This is his second full early season (i'm excluding the early season he went from Junior to profs for obvious reasons). So yes, he never had a better start, but on the other hand its only the second time.. so don't know how much weight that statement has as such)
But my answer was more directed to the statement of Roglic having the best ever early season form.
For example I can't remember when was the last time Roglič did a worse ITT than the one in T-A this season. So rest assured, he has still more room to grow.
