Question: TabPFN-3.5-fast better on TabArena multi classification than TabPFN-3.5?

Hey, I was looking at TabArena results of the TabPFN-3.5 and TabPFN-3.5-fast and I was wondering why TabPFN-3.5-fast has a higher elo than TabPFN-3.5 on multi classification tasks. Mainly I want to know if you have any insights as to why it performs better on this specific subset of tasks as it is quite counterintuitive and on all other tasks the full TabPFN-3.5 is (expectedly) better.
