Highlights are
- Long term planning is often overly restrictive, and doesn't allow the lifter to deviate to take advantage if they are progressing more rapidly than expected
- More traditional periodization assumes some amount of knowledge ahead of time on weaknesses and assistance work to address that, whereas this approach allows rapid testing and evaluation of what is driving progress
- Requires much more detailed tracking of variables and some more advanced data analysis, that may be better automated (incidentally, exactly what the RTS app can do)
Given some of the other discussions going on in the strength world, this is definitely an interesting take on the programming problem, and I think a step in the right direction toward "optimal", since that seems to be a big deal these days.
