OTB, RO, and XG evals are wrong here

OTB I thought this was a very strong recube since I have 15 superb shots to make a 5 pt board, and since if I fail to do so, everything else creates more builders. I was honestly unsure whether this was a take or pass, but felt likely a bare take. This overestimate caused me to wimp my 2 last turn by playing 14/12 rather than 13/11 getting a direct 6, but leaving two more blots.. ie a clear error.
Anyhow..my opp passed so all was good.
I was suprised when XG evals (4 ply and XGR+) dinged me for this recube and the rollout shows my recube is clear, but a clear take.
This is the type of late blitz position where XG is consisantly overvaluing the trailer's chances.
