Got back my racket from the stringer and i noticed it kind of strange of his stringing pattern. Usually the stringer did a 2 point tie off but this time its 4 point tie off. Is this the correct point of tie off ?
In the yonex catalogue you can find the stringing patterns. The knot in the top is a little bit off, but it should also work.
It is so far from the last cross that there is a very long untensioned/barely tensionned string segment. That tension loss creeps over to the last couple mains. Also, it lies along the area of the racket that is usually used to pick up shuttles, so that part rubs on the floor quite often, which causes damage on the string over time. It could be ok if there was any advantage to it, but I don't see any. Maybe some other people can find some though.
Knots should be tied as close to the last string as possible. Some stringers do tie the top knot at the 2-10 area - we have very famous one on here - but I see no advantage. (I've been told it keeps the knot away from the sweetspot mains, but with 20-odd crosses going through those mains, how much difference will a knot make?)
If possible, i like to put my tie offs on the closest string that goes the other way in the grommet, so if it does slip any, it can't pull all the way through since the anchor will hold it.
