I have experience with wagering 250,000$.

Take a lot of money, IMO don't focus on the VIP even if you have only 10% left. Just keep playing as usual chasing for winning, not wagering as you know you can pursue both (choose one).

Once you chase wagering you need to sacrifice some balance for that. Just chase at the time your VIP Progress only under 5% maybe 3/4% should be enough to chase the waggering.

More than 5%-10% are to high for player like us.
