Okay, after spreadsheeting it I've got a fairly good idea of what the solution looks like on greens.
Phase 1: 0% hold (100 colonists on the planet, but overflowing as normal)
Phase 2: 25% hold (i.e. colonists on planet + overflow growth = 25%)
Phase 3: gradually creeping up from 25% to 50%
Phase 4: 100% hold (yes, there's another discontinuity)
Phase 5: gradually creeping up from 100% to 300%, ending at the final 300% hold
Phase 1 only takes place on low-hab planets (1-55% for the usual 19-20% growth), as the formula from my last post implies. High hab also extends phase 3 substantially in both directions, which is somewhat intuitive as this is the phase where planetary growth is highest.
Having factories accelerates the progression through to phase 4, since 300% hold doesn't boost factories and as such 100% hold is prioritised. For factoryless races the holds are surprisingly low - it's well past 200% population available before a -f goes to phase 4, and on low-hab planets even the 25% hold might be delayed until there's 100%+ available.
Phase 5 is controlled entirely by growth rate; factory settings and hab are irrelevant, as the planet is already 100% full. Phase 5 starts when:
pop = 2.92 + 0.16/PGR
and of course finishes at:
pop = 2.76 + 0.48/PGR (this being the amount of pop needed to sustain 300% hold)
