Strength for reps is different than the power for explosiveness. Progressions for explosiveness is key, you don't have to do clapping push ups at the start, do plyo push ups without the clap. There is no definite answer to this but explosive version of an exercise is far different. As for the clapping push ups, after you master plyo push ups, start doing the hip motion clap push ups, where you use momentum, and then do it with no momentum which is obviously the best for strength gain. Also you're "less explosive" if you have more fat, so losing it will make you more powerful and make the explosive part easier (as well as bodyweight exercises will be easier). But practice bro, you can't make it better without practicing it, even if you can do only 2, get a set & rep range, like 3-6 sets of 2-8 clap push ups, and do your max effort without momentum and then finish them with momentum.
