Hi Dadanawa,
You did bother to draw this circuit out before posting your maths - didn't you?
If the downwind heading is 281 degs and the wind is from 269 degs at 10 kts, why are you bothering to circle to land with a 10 kt tailwind on finals?
If the circling direction is Left hand circuit (/L) why are you turning Left (253)? You would then surely be turning Right to turn onto finals. (What we used to call a Right Hand Circuit).
If I was flying at 1500 ft agl I would fly from abeam THR to base turn for 45 secs in still air. Since I have a 10 kt headwind flying downwind, then I'd turn at 55 secs (not at 33).
I think you'll find you need a mental picture to fly circuits - not a list of numbers.
