Please help

I have always been under the impression, and past experiences have also proved to me that you are not able to take a percentage when taking the tote double... If this is still the case, please could someone use simple English to explain to me how if you cannot take a percentage DB on the tote, how do they get a percentage carryover?

Young Race 5+6 double

DB 1x4,6
101.20
DB C\O
120.90

Thanks in advance.... I am obviously missing something somewhere..

We co-mingle into tabtouch
Double (5,6) 1-6
Partial C/O 101.20
(12.09)
That is on their site.
The double pool was only 63 dollars

Thanks Durbs, so if the Double pool was only 63 dollars, why was some/most of the will pays over 1K?

Are they able to take a percentage on the tote Double in Aus?

Honestly I don't know.
And I'm not sure how some will pays where paying over R1000 as the pool was only R506.

You just never know what our tote are doing anymore,they just chop and change as the feel and there is nobody out there to check if they doing things correct.
Two jackpot pools where reduced by around R10 000 after the all clear in the last few days with not even a comment by them why that happened.
We cannot trust the tote anymore that's for sure.
