Since 2012 I used to bet same amount of bets for each tourney, bet on WTA and challengers and doubles, also live bet but this year I am making early plans, arranging as much Bankroll as I can so I can bet heavy and comfortably come Masters and Grandslams.
This year I am skipping WTA, doubles and livebet altogether, also skipping challengers most of the time with the talent involved and possible "fixing". Still if I like a bet I play occasionally. With 250s or 500s I still wager, I have less total volume definitely but occasionally if I like the bet I go as heavy as 4% of my bankroll, around $1000.
Since I adopted this technique in 2014 I made approximately $15K. My best profit in 2 months time. I read somewhere to withdraw your earnings on the exact day on the exact time weekly. Monday 09:00 A.M for me. So my bankroll is fixed around $22K to $25K, approximately half in bookies half on my bank account. I also try to buy something nice each week if I withdrew money. It can be sports supplements, watch, designer clothes or some electronical device. It does not need to be something over-board, I enjoy the feeling.
Also I stopped betting on basketball, cricket and soccer. All my concentration, time and bankroll is committed to tennis. People say capping tennis is harder but quite the opposite for me. I cant cap a basketball game and learned to be ok with it
