Worst CSF dividend ever?

could be a mistake/ last race newmarket  5/4 winner 6/1 2nd  paid £10, and less runners.

It may be a mistake, but nobody's rectifying it and there's nowhere to go to verify the calculation, so what can you do?

To put it into perspective, here's a couple of others from today:

Market Rasen 2:20 (7 runners), 2/1 beats 10/3, dividend = 8.23
Limerick 6:35 (12 runners), 9/4f beats 11/2, dividend = 16.64

....and from yesterday

Ffos Las 6:05 (8 runners), 11/8f beats 5/1, dividend = 9.51

I feel robbed :(

Id ring up the Post at least Mystic, ok there was a 5p rule 4 but it still doesnt look right at all

the only thing is do the non runners make a difference, but this does seem a low return.
