Unusually High efficiency? When Pils is involved?

[HolderHouse]

Good morning brewers

So yesterday I brewed a Durtmender Export from BCS. The recipe is as follows and did some math for my total points (weight*max yield)

8.5# Pilsner Malt (8.5*37) 315 ***edited MO***
4# munich (4*35) 140
3oz malanoiden (.185*37) 7

total points: 462

Ok so here's what I collected: (measured via blichmann sight glass at 4% expansion temps, no adjustments)

Preboil volume: 9.25 ish
Gravity (stirred to mix after mash): 1.051

I was shooting for 1.042 so I added 1 gallon of water to hit my mark, but 51 points is way high. When I did the math, hopefully correct, I came up with this:
51*9.25= 471 points total BUT that's higher than the total maximum yield for the grains.

what happened?
Have you seen this before?
Do you think the home brew store gave me too much grain (like 1.5#)?
It's been driving me crazy, guys and gals; feedback would be appreciated.

PPG for MO could be 38-39, so could the Munich. You need the malt analysis, but 82-83% is normal.

that makes scene. the MO was actually pilsner malt. That brings me closer to 95% I was going by the yield in beersmith. I will have to look up a malt analysis for what I ordered.
