Sorcery Points Conversion Rate

[dokugin]

Working on a magic system based off of the sorcery point conversion rate from spell slots to Sorcery points and sorcery points to spell slots.
The PHB only goes up to fifth level so wondering what people think of this conversion rate.
1st level spell slot - 2 SP
2nd level spell slot - 3 SP
3rd level spell slot - 5 SP
4th level spell slot - 6 SP
5th level spell slot - 7 SP
6th level spell slot - 9 SP
7th level spell slot - 10 SP
8th level spell slot - 11 SP
9th level spell slot - 13 SP

The DMG (p288) actually has a variant rule for Spell Points instead of Spell Slots, and it has a specified cost for the level you cast your spell in (the spell slot). If you hadn't seen that yet, good job expanding it; it is spot-on! ;)
