Loamm Roamm Reverse Gold Time Change

I’ve been watching vids on youtube showing people completing this race by beating a time of 52.000 sec for the reverse Loamm Roamm race.

But why is it now 48.000 seconds for gold?

I can’t even break 50.000 sec at the moment and I’ve watched most of the most recent vids on these. (all beat 52.000 for gold) Why was this changed to such a difficult time when I also have no issue getting so many other golds?
