Just a thought but, I would suggest an overtake needs to be completed within one third of the distance seen to be clear.
If you make it 50% it doesn't take account of the oncoming vehicle/motor bike that may appear a fraction of a second after you've committed to the overtake. 50% may mean a tight squeeze to get back in or the oncoming vehicle has to brake to let you back in.
Additionally if the approaching vehicle is travelling at a higher speed than you, when it appears, then allowing to get back in a third of the distance rather than half is more than wise.
