Great question, but a difficult one to answer without seeing your technique. Experience, Skill and level of athleticism differers greatly between everyone. Also some have better kicks and need more work on their boxing. or even time commitment to the training!
I would do the episode, and if you feel great with the technique/concept move on. If you are still feeling off, head over to the tutorials and focus on the strike that you're having difficulty with, then do the lesson again and see if it improves.
I also think it's important to revist the same episodes every so often. When ur learning you miss a lot of details that you will pick up a second time with more IQ and competence.
Last tip, would be focus on units. Maybe weekly, bi weekly or even monthly focus and improve one aspect (kicks or punch or knee etc) rather than jumping all around. Like traditional schooling learning blocks helps with retention!
Hope this help!
