DETAILS OF THE FUNCTION OF MY BACK/LAY SAVERBET CALCULATOR PLUS AN

 EXAMPLE OF A BACK/LAY SAVERBET WAGER. 

1. A  saver bet is one where you make a prime bet with the intention of winning , a saverbet is one where you have no intention of winning , you are only interested in covering your stakes if your prime bet loses .
2. A simple example of a back/back saver bet , teamA is at the odds of 2.00 to win a match , teamB is at the odds of 4.00 to win the match.
3. I wager $100.00 on teamA and $34.00 on teamB to win 
4. If teamA wins I win 100.00 less my 34.00 stake on teamB
5. If teamA loses , teamB must win ( forget the possibility of a draw ), I have 34.00 at 4.00 on team B to win . 
6. In this case I will win 136..00  and my 2 stakes are 100.00 + 34.00 so I will either win on team A or I will get my money back for the win by teamB

8. This is an example of a simple back/back saver bet.

10. My problem is with a back/lay saver bet. 
11. A lay bet is one that can be made on a betting exchange , betfiar.com.au for example and you can lay a team to lose , you are in fact acting as the bookmaker.
12. Using the same odds in the example above TA & TB , assume  I want to make a back/lay saver bet on team A .
13. I wager 100.00 dollars on teamA to win , if it does win I win 100.00 
14. I want to make a lay bet saverbet on teamA , I just want to wager enough to cover my back bet on TA plus my laybet liability .
15. I believe my lay bet wager should be 34.00 and if my lay bet loses as far as I am concerned it is a losing bet , am I correct in saying my lay bet is 34.00 z 4.00 or am I missing out somewhere .
16. That is the question , is my thinking correct ?, the worry to me is that it is the same as an ordinary back.back saver bet .
17.  If I am wrong what should my saverbet be , to repeat I do not to make any money on the laybet , it is only made to cover my prime bet on team A if it loses.
