I honestly have no idea how custom cams are even chosen. There's so many variables going on that the only way to really KNOW which cam is best would be to try EVERY single one for a given combo. There is no way to 'calculate' the optimal cam.
I would hope the prospective engine builder would do some research- heck even call one of the tech lines at Summit, Crane, etc. or jump on a message board. Even if he used one fhte tried and true cams say a TFS, Anderson or Crane OTS cam and then get the custom cam and see what difference it would make.. We're talking about your average build= nothing exotic- like a stock bottom 302 with a new TFS, AFR, or Edelbrock top end. The same buiild thats been done 10000 times. Even a 347 with a decent set of heads.
My engine builder doesn't own a computer.... He has a rack of paper catalogues and no internet... This is a win for me, he isn't so involved in the YellowBullet drama and is busy building what he know works. Years of experience building high performance engines will easily surpass the knowledge that you can find via the Summit tech line, those guys are hardly worth the time of day when seeking advice on anything.
My first custom cam had chev truck big block intake lobe and ford small block exhaust lobe.
Think you are going to find that on a shelf somewhere?
Cam I have now has "super stock" lobes, runs to 7500rpm on itty bitty 140cc heads but runs fine on the street and makes plenty of vacuum to run all accessories.

Yes, those are extremes, yes, that what custom cam designers can do.
This is a great example of a custom cam guy
I cannot believe that this thread is still going. You know what this means? None of us know chit about cams.
I for one, pay to have mine chosen for me.
actually i learned about cam selection from two of the best, david vizard, and denny wykopf. both of whom were instructors of mine when i was in college studying automotive technology.
