I 100% agree with Brent
In the end, assuming they hit their numbers, quality is good, and the cores are available etc, IMO these are certainly a little better than most of the common off the shelf cams. No idea why their numbers are off, but you are correct. Could be an asymmetric lobe, differences in putting a lobe family on an FE core, or just bad documentation or a combo of all of it.
However, with these cams for the discount, you give up lift, which likely drives some spring choice changes as well as the obvious flow loss. You give up some seat-to-seat timing, which with a normal retainer and 3/8 valves will want some extra pressure. What I don't like is you have to go small to get overlap low enough to have decent vacuum on a street build, it'd be nice to have some wider LSA options.
Assuming the lobes are controllable, some spread on those bigger cams would be better for a stroker but given the lift and seat timing it'll still be a power cost over a custom. Saving 200 bucks is 200 bucks, but it comes with a cost.
On the flip side, there seems to be some decent split, good for stock or TFS heads, although maybe a bit excessive on a couple.
I would be hard pressed when digging deep into all the other blueprinting to recommend a generic cam, but if quality and availability holds, I can see a market for these
