I guess it makes sense that once a design decision is made to slope the rain gutter for good drainage while on the ground, to then fine tune the slope so that it offers the least amount of drag while in flight.

Suppose the fuel cost is 1kg per sector. That's (short haul) 2000 kg per year- several hundred pounds.

Just because you can't measure it doesn't mean to say it isn't there. Otherwise they wouldn't bother cluttering the aircraft up with all the CDL bits and pieces in the first place.
