My success rate is very good, could be for a variety of reasons: the bees themselves, the attention I give them, geographical location, removal method, type of equipment, how they overwintered etc...
The more mistakes you learn from the better it gets.
Our bees here rarely abscond but I know other beekeepers whose bees can't stay put and queens have to be clipped.
Ask yourself why those hives absconded? Why didn't they make it?
There will lie some of your answers.
