How much decking is to much?

Decking parallel and square decking are two different things on the price sheet ;) . That bank will crank even at least ... so they're half way there. Lol ...but i agree with you, I'd have told them to go mill the other side the same and basically chastise them for being lazy and thoughtless.
Amazing.

That's true, but one should not be done without the other, IMO. What's the reference for anything with the block deck? The crankshaft center line.
