Realistically, you should have a steady supply of SRs by the time you care about skill lv 21 and beyond. As by then, every new SR you pick up is fodder. If you are actually still filling out your grids with new SRs, you're not at the point to play with final limit breaks yet. So at this stage, it shouldn't be hard to pick up 8 SRs from advent event exchange, 9 SRs + whatever you roll from raid gacha (I like to keep a maxed copy of the raid kamihime weapon for collection purposes, but that's not practical), and 8 SRs from union event. And then there's whatever SRs you pick up from farming disaster ultimates/our ragnarok raids.
1x R = 10 points
1x lv 3 R grail = 60 points (after spending 1+1=2 R's, or 20 points)
1x lv 4 SR = 140 points (after spending 1+2+3=6 R's, or 60 points)
1x lv 5 SR grail = 250 points (after spending 1+2+3+4=10 R's, or 100 points)
1x lv 2 SSR = 700 points (after spending 2 R's, or 20 points)
Lvl 20->21 needs 400 points
Okay-ish amount of R grails and SRs still lying around? 2 lv 3 R grails and 2 lv 4 SRs will do the trick.
Lvl 21->22 needs 420 points
3 lv 4 SRs handles this exactly. If you don't want to spend the 3rd SR, substitute it with 2 lv 3 R grails + 2 R's, or 1 lv 3 R grail + 8 R's, or 14 R's
Lvl 22->23 needs 440 points
See above, then tack on 2 more R's
Lvl 23->24 needs 460 points
See above, then tack on another 2 R's (so it's the lv 21->22 enhancement + 4 R's)
Lvl 24->25 needs 480 points
3 lv 4 SRs + 1 lv 3 R grail, or replace the grail with 6 R's.
Lvl 25->26 needs 500 points
See above, then tack on 2 more R's. Alternatively, 2 lv 5 SR grails comes out to 500 points exactly.
Lvl 26->27 needs 520 points
See above, then tack on another 2 R's (so it's the lv 24->25 enhancement + 4 R's)
Lvl 27->28 needs 540 points
3 lv 4 SRs + 2 lv 3 R grails, or replace the grail(s) with the corresponding number of R's. Alternatively, 2 lv 5 SR grails + 4 R's.
Lvl 28->29 needs 560 points
4 lv 4 SRs. Or 3 lv 4 SRs + (140 points from combination of lv 3 R grails and plain lv 1 R's). Or 2 lv 4 SRs + (280 points from other combination). Or 2 lv 5 SR grails + 6 R's.
Lvl 29->30 needs 580 points
4 lv 4 SRs + 2 R's. Or 3 lv 4 SRs + (160 points from combination of lv 3 R grails and plain lv 1 R's). Or 2 lv 4 SRs + (300 points from other combinations). Or 2 lv 5 SR grails + 8 R's.
