Besides, just looking at BSFC smacked us up against the tallest gear available, so there didn't seem to be any purpose nerding out over it any longer. Does it really matter if the ideal gear ratio is 10% taller than the tallest we can get, or 15% taller?
Educate me if I'm just being dense.

In a Nutshell, that BSFC (Brake Specific Fuel Consumption Chart) and all others measure Fuel used at RPM with Max Load; so unless you guys are planning to tow something rather boxy around you will be turning the ALH far to quickly.
If you check out the Gear Threads on TDIClub you can get a idea on what gears do what (atleast with the MKIV body).
However with (what I can only assume) will be a low drag shape you will want to turn the ALH much slower, unless you just like P+G.
