My maths is a bit rusty, but isn't that around 0.05%?  
Asking a lot, but good luck with it.
My feeling is that things like gate openers are built to be big and bulky and forgiving of things like dust and grit build up in the grooves- not so observatories!
As you chase down the last irregularities hopefully it will all slide together for you.

All problems come because a roof is different to a gate.. frankly I had never noticed before...the big problem is expansion and contraction of the roof due to change in temperature I expect...if the worst comes to worst I will add a single bed and stick the gate motor on my front gate.
