I am not sure it changes that much with the new alignment. Just put FCL as a combined GCL/NY Penn level. Just about any HS or Latin American mid-level prospect will repeat FCL anyway. Only a matter of time before they make it a full season league.
FCL - age 18-20. Never really appropriate for college picks other than introducing them to pro ball.
Low A - HS/LA age 19-21. College draftees age 21-22
High A- HS/LA age 20-22. College age 22-23
AA - HS/LA age 21-23. College age 23-24
AAA - HS/LA age 22-24. College age 23-25.
Definitely a wider range now with the pandemic jumbling things up. I also think the upper age ranges might tighten down a year for some levels when we are beyond the pandemic and development gets back to normal.
Painter should be FCL this year and Low A next year. Any other HS pick or Latin American pick is probably fine repeating FCL. Wilson if he is treated like a high, fast moving college pick basically starts at Low A but should be in High A Jersey Shore next year with a shot at AA by the end of the season.
Things will seem more normal next year. This is the first season of the 180-player limit and the Phillies are probably feeling their way through the proper distribution of prospects at each level. I think the end project might be a year younger than I laid out because the 180 limit will force us into earlier cuts of C and B level prospects that might have hung around the older system. They will now get cut after a year and a half and then bounce to an independent league. The Tyler Gilbert path might be tougher now. He could easily have been a cut a few years ago in this newer, harsher system.
