Basically you are giving yourself an edge. A 2knl player playing 400nl with an ev stipulation makes this a straight can you play a 100k hands in a week bet. Anyone willing to bet on this, which I was, would have to know you personally and have a strong inclination that you won't be able to do 100k hands in a weeK.

While doing a 100k hands in a week is quite a feat, it is less impressive given achievements of others before. Chichago Joey set a record by completing 50k hands in a day. An achievement that lasted less than 24hrs. Since Joey I think 3 other people have done it. So nobody is doubting that you can play 100k hands in a week. With enough money bet against you quite frankly i'd be surprised if you didn't. There's certainly nothing epic about it.

The real incentive for the bettor is whether you can do it profitably. One of the real interesting things about the bet is the variance and how you deal with it emotionally and mentally. Some guys go on heaters straight away and are basically a lock for the bet. Others hit one bad day and start to doubt themselves then give up. Making ev a part of the bet removes that part of the challenge for you. Of further assistance to you is the ability to play higher than 2/4. Again this give you an out. You can play like a nit/ run hot at 25/50 to cover all your losses at lower stakes and just get in the required hands to win the bet.

If you are serious about making an actual bet... you will play all your hands at one stake i.e. $2/4 and you will remove any talk of an ev stipulation.
