Pick 4 Budgets

I'm curious to see what pick 4 players spend on the pick 4. What's your budget? I used to only spend up to 100 but I've increased it to around 150 and I've been hitting allot more of them. I play mainly Hollywood but also the major tracks around the country. I wonder what the average payoff for the pick 4 at Hollywood is. That might be a good indicator of how much you would want to spend on the pick 4. Of course the size and competitiveness of the fields has allot to do with how much I spend. If it looks like it will pay good I'll spend a little more. If it looks a little chalky I may play a cheap ticket a few times.

What's your stratagy?
