Not bad...not bad at all. The only thing to consider now is whether or not that combo would've been included in your new list... and it's where timing and efficiency both come into play specifically with small combo lists. For reference's sake, let's crunch the numbers based on the $13.50 and six draws out inclusive of only the evening draws as mentioned for a 3 way box hit ($80). On the June 14th midday draw they hit so you start that evening.
6/14 Eve-No Hit (-$13.50)
6/15 Eve- No Hit (-$13.50)
6/16 Eve-No Hit (-$13.50)
6/17 Eve-Hit (+$80.00)
Now, here's how it works with the bankroll factored in like I've talked about so many times. You START with a bankroll of $80 which is also the amount of the payout you're playing for and affords you those six draws to play. $13.50 x 6 = $81 and you can kill off two combos to bring it to the square $80. So, you played three times for a total investment of $40.50 before you hit and, simultaneously, recovered that $40.50 while also turning a profit of $39.50. The $39.50 also compliments what you had left after having played those three times. So, here's the new tally on finances:
$40.50 recovered within the $80 payout.
$39.50 remaining + $80 payout = new total of $119.50 to work with.
The$119.50 now represents a new total of eight draws to hit within...$13.50 x 8 = $108.00 and it also reflects something else that is both very important, and, VERY ATTRACTIVE. If we subtract your original $80 from the $119.50, we find $39.50 which is that same profit AND A TOTAL OF THREE CHANCES TO PLAY COMPLIMENTS OF THE STATE (HOUSE). $13.50 x 3 = $40.50 (you can kill another two combos for -$1).
I know you plan on reducing the combos (cost), but this is just to show you how the numbers work based on this set. Not sure if you've ever crunched numbers like this before, but it's what I do every day and have for years...and I'm very good at what I do. I take my money and these games very seriously and so should you...especially now that you have something promising to work with. The main difference in us will be that folks will flood your PM box for numbers and access to your system 'hook-up' because it'll be within what they may want to spend. The major difference in me and other 'number scholars' around here is that I crunch ALL THE IMPORTANT NUMBERS and not just round up combos. Otherwise, a player can't accurately know just what the hell his money is really doing over a period of time. The reason I did this is because I honestly enjoy it and wanted to help you learn how to properly manage your funds for your system and stay ahead. I'm not implying that you're incompetent or anything like that either, okay. I just want you to see the importance of how all the numbers should look, start to finish, from someone that knows EXACTLY what they're supposed to look like with this style of play. In all reality, the entity issuing your combos should be providing some level of support in this regard. Even so, should you ever need a hand with more crunchin' just holler!
Best of 'skill', buddy...with just a splash of luck!
P.S. Be very careful with how much you reduce your list.
