The practice grid is no substitute for a compás
The list deliberately begins with the strongest counting aid and ends with a pulse carried by someone else. What stands out is that the position in between stays the same, while your orientation becomes more independent. You can tell a solid exercise by the fact that you can leave out the extra beats without changing the pulse. That is more helpful than managing to clap as many beats in a row as possible.
The numbers one to four only structure your practice here. They neither determine the accents of a palo nor explain its musical phrase. When you later add the pattern to a marcaje in Flamenco Tangos, its counting and sequence of movements remain your points of reference. Your additional layer must not displace them.
First, practice the transition with a recording whose basic pulse you can already follow confidently without Palmas. Listen to a phrase, quietly add the positions in between, and leave them out again before a transition you are still unsure of. Stopping is a deliberate choice, not a missed cue. With live flamenco, for example on the small stage of a tablao, also listen to the musical situation: a steady practice grid is not an invitation to clap through every open space.
