Dan I'm not sure how big your lab by line units are but for a 2 game chase my unit size could be 20 to 30 times bigger than a 5 game chase unit size.
Understand. I think both ways can be very profitable. With this win% with very low juice I'd increase my number on both a 2 game chase and labby line. With the labby line I wouldn't give back anything on the 54, 2 game chase losses. Makes it harder to track and it can get complicated with a losing streak and multiple games but it can be done. A strict 2 game chase is much easier to bet.
