Possible stage orders are
1-5-10-20-35(All1)
1-5-15-20-35(All1)
1-5-15-30-45-RB1-RB2(All3)
1-5-15-30-40-RB1-RB2(All3)
1-5-15-20-40-RB1-RB2(All3)
Then there's going to 50 from stage 40 or 45 instead. This will lead to an All2.
All3 is the best possible clear, while All1 is the worst one. There's also 2 seperate All3 types, but clearing Real Battle either way is an All3. If you die during Real Battle 1, you will get a 1,000,000 point clear bonus if you clear. However, if you don't die in Real battle 1 unlocking the TLB requirement and 1cc, it'll be a 10,000,000 point bonus.
