I do 20k stacks, 20 min levels, no antes.
100/100
100/200
200/300
200/400
300/600
400/800
500/1000
600/1200
800/1600
1000/2000
1000/2500
1500/3000
2000/4000
2500/5000
3000/6000
4000/8000
5000/10000. Game should max out here around 6 hours with 5 min breaks.
If that's to long you could do 15k stacks and 18 min levels which should shave an hour off.
