They're both for after you've completed ROP (5 ladders of 1-2-3-4-5) but are still not ready to move up to the next size bell. It is still simple and achievable, but now rather than flailing around looking for the next program because you're not ready to run it again with the next bell, you have a clear progression that works and keeps you focused.I think these are clever options, but why complicate? Keep the plan simple and achievable. If the plan with a 20 is too easy (which my feeling is that it is not too easy) what's the harm in that? No risk at all, but you are guaranteed to be ready for the 24. Adding and pushing it induces tons of risk. What's the benefit? Best case you maybe save a few weeks in a lifetime pursuit? Not worth it in my opinion. The more probable outcome is discouragement and setback. Enjoy the process. Master your technique. Finish the plan as written.
For me, it is not complicating the program but extending it while maximizing the amount of training you can do with a single bell. Providing a progression like this shouldn't contribute to discouragement - you have a path to follow and guideposts along the way.
Everything in Option 1 came from recommendations by Pavel in the past when you weren't ready to bell up (next bell was too heavy) or couldn't (lack of availability of the next size). I think the W:R idea originally came from @Geoff Neupert but I found it from a recommendation by Pavel who attributed it to him. Option 2 I stole from @Hector G but he was using it in a different context - but I have used it here successfully as well.
