You shouldn’t focus on 1 frames until you have a BnB down. Because if you don’t have a BnB down, you can’t play the game to its fullest potential. God forbid you’re playing Vega or Gief where their BnB is all derpy 1 frame jabs/shorts. If someone is having trouble with cl.mp -> cr.hk, they should work on that combo and get it consistently before they even think about 1 frames.
cl.mp xx lp hado can be uppercutted in between hits on block
cl.mp xx lp hado -> sweep is character specific
On the characters it works on, it only works on a few of them if they’re crouching
You can’t do walk forwards cl.mp xx hado because of shortcuts giving you cl.mp xx palm (not the worst thing, but still not what you’re going for)
Gouken can set up a crossup that can’t be reversal uppercutted off every sweep he lands. Combos not working off crossups is a big deal for him.
Going from a normal, to a special, to a normal means that your timing can be changed based on the timing you actually get the hado as compared to when you input it (aka the buffer window can screw up your timing). The timing in between button presses for cl.mp -> cr.hk is always 100% consistent unless you plink cl.mp for some reason.
Learning cl.mp -> cr.hk segways into cl.mp -> cr.hp xx EX Palm, Gouken’s most important combo. The frames are identical between cr.hp and cr.hk and in 2012 this should work basically always unless the cr.hp is out of range. In which case cl.mp -> sweep would work, but not cl.mp xx lp hado -> sweep.
Gouken’s offense is stronger off a raw cl.mp on block than it is off a cl.mp xx lp hado. He has to go to a zoning game on block off a hado. The best frame trap he has off blocked hado is walk forwards s.hk, which is very slow and focus bait. Off cl.mp he has kara throw (hk is kara throw), sweep frame trap, cr.mp/cr.hp xx demon flip, cr.hp xx fireball hit-confirm fadc sweep, far s.hp/s.mp CH combo to sweep, the opportunity for a crossup, and frame trap kongo shenanigans. Most of this disappears off cl.mp xx lp hado on block
Linking off a hado is a very useful skill for Gouken but it’s situational. People need consistent BnBs to start with.
And personally I know people who hate practicing combos and never get better because people always tell them “you either can do 1 frames consistently or you are free” so they don’t even try. When if they learned how to play with some simple, consistent combos, they could incrementally learn the value of the difficult stuff and fit it in where they find it comfortable for their gameplay style.
