(also @pjk it would be pretty useful to have an inbuilt scramble generator thing for these threads(not forcing you or anything, just an idea))

wanted to do all 4 paths but 6CP and APDR got fused into each other and CDRLL and JTLE got fused into TDR.
Nice scramble btw

this goes to show that EOLE isn't that much better than insert>EO in terms of movecount but it does create a big difference in terms of reducing pauses.

Although this is just one solve, this is the conclusion I have come to as well.

On average, if your belt is efficient, you save maybe 1 move due to EOLE. But EOLE made my belt solution so much more concise, and the whole solve flowed much better as a result.

EOLE sucked here because it didn't allow me to preserve DFR; I wonder if I could've keyholed the solved corner out of the way to preserve it... Probably.

I agree and you could have keyholed the corner out of the way

u' U' D' R U2 R' F' U F //EOLE
D R' U' R U2 R' U R U' R' U' R //DCAL
F R2 U' R2 U' R2 U R2 F' //CDRLL
S' U2 S U S' U2 S E' //L5EP

also, I wonder how useful learning all the TDRs for the worse DCALs(like the one above) would be.
It's just like how you learn all the ZBLLs, OLLCPs or 1LLL for a case where OLL>PLL isn't the best thing to do(eg. F R U R' U' F' into Pi 2GLL for the Collin Burns OLL diag swap case)
