Wtf was that scramble ??? Too many emotions
First minute I noticed huge blocks and 3 move EO preserving some and found a 7 move DR
R L2 B, R U L2 D//of course it's 2c5,

Then realised there also is a 2 mover and 6 3 movers, even the 6 bad is goated.
My expectations were so high I didn't check half the 4 move EO's I wrote I mean every 3 mover was RZP or JZP or at least blocky ! 

But then nightmare : I was expecting 18 on this scramble but only one DR with very good subset : 4b2 2e in 10 with HTR in 14.
I was ready for a fight against the 7+5  for a 22 at 45min but this 2c3 reduction looked too good and I got a stupid slice in 20 saving the attempt.

What a surprise Mallard does not find a realistic sub 20 and all my DR's are sup 20 optimal what did I miss ?

EDIT : Looking at Louis's solution, I realized that I forgot to check this HTR on this variant because on first 2 variants it was bad and the other one gave 21 to E slice :(
