How's the rush in SL class of Raptisagar Express?

Hi guys, I hope you all are doing fine. I'm thinking to book a sleeper class ticket in this train in the month of Feb because it's the perfect train according to the timings (check GDYA to CNB). However this train is very popular for the rush and WL/General ticket passengers to occupy reserved coaches (I've seen that it's SL is like general coach and so on). Also it's one of the most profitable trains running through this route in terms of money earned through TT's in train during journey, you can just imagine how heavily rushed it would've been. Now there's been this rule from few months that WL and general class passengers are strictly not allowed in reserved classes (WL passengers are not allowed to board the train). So I want to ask fellow railway community, how's the rush nowadays in Raptisagar Express? Is it like before or the condition is now changed and one can book their ticket without any tension in mind in terms of rush and all. Thanks :)
