Both levels require exactly the same number of overworld movements to reach and then proceed to 5-F. It's not like 5-3 is some RNG-fest that saves massive time if you win the lottery or anything similar that would provide incentive to create a category specifically for one level or the other. In fact, the level would be longer but for an additional pipe loading screen in 5-2. Time: 5-3 saves only a few seconds over 5-2. There is no hard skip or trick to merit creating a more beginner-friendly category. However, with a bit of practice, either level is pretty reliably doable. Difficulty: 5-2 is easier to keep prop through than 5-3 because 5-3 has the annoying and poorly programmed Bramball enemies. Really, there are no substantial differences at all except for difficulty and time, both of which are extremely minor here and not worth splitting categories for. There is no difference in the powerup route between 5-2 and 5-3. Not sure what you mean by 'compensate for RNG.' You always have to fight the piranha after 5-1 unless you die, and if you're dying in 5-1, you should probably just play 5-2 and call it a day. Separating any% into 5-2 and 5-3 branches would be a bad idea for a few reasons:
