slight bend in headstock

[Homebake]

i've noticed there's a really slight bend in the headstock of my rg2550z. looking down the headstock, towards the high E tuning machine, the wood has a slight concave in it. the end of the headstock curves ever so slightly and the back of the headstock, where the tuning heads are, if you look down the line of tuning heads, there is a reaaaaally small curve as well.

it's a really, really small concave but i'm wondering if it's going to get worse or something? you can only see it if you look down the headstock and only if you're looking at the right angle. is this a common thing on rgs?

here's a diagram i drew quickly to illustrate.

looking down onto the neck, that's what i mean by concave bend. it's not as extreme as that line, but that's the idea.

Strng tension maybe? Could be pulling on a weak spot.

Just an idea... Don't take my word for it.
