It would probably depend on how fast you can get the BLJ off. If it does save time it won't be much and it would be too inconsistent unless you're a Dowsky clone. Not really worth imo
That BLJ has been known for a while. If it would save significant time, runners would have already tried incorporating it into their runs I think. If it saves time at all as you are also dependant on the cycles of the rising platforms. If you get onto them, but have to wait for them to rise, that would not save any time at all.
We would like to announce that VC and EMU subcategories are now active on the Stage RTA leaderboards (under "Levels"). Stage RTA involves collecting all the stars in a given stage including the 100 coin star. Timing starts on star select and ends upon collecting the final star. You are allowed to us
