Tennis Automation Rule - Back Half Stakes at Double The Odds

[karlm]

Hello,
I am trying to create a tennis rule to back half my lay stake at double the odds if the 1st set goes to 3-3. Please can you help.
For Example, If I lay a player at odds of 1.3 with £10 at the start of the match, if the 1st set goes to 3-3, I want to back that player with £5 at odds of 1.6.
I've tried using the stored value feature to create a value that I can use later on with a condition that the game goes to 3-3 to do this by taking the value of the lay price for the player when placing the lay bet (automated) and using the Adjustment part to multiply these odds by 2. However this gives a a value too high, ie 1.3 X 2 = 2.6 but in odds terms it needs to be 1.6. Therefore I need to multiply the odds layed at by 2 and subtract 1.
Hope this makes sense and I look forward to your reply.
Many Thanks
Karl

On the stored values tab in the 'Adjustment' section use
Plus
a percentage (using -1)
100%
