For about 1-2 weeks now LeoVegas odds have been 0.01 or 0.02 lower than the ones Rebelbetting informs me, or the previously similar odds with PAF/Unibet etc.
I understand that its totally possible for two bookies using the same odds have different margins, but the weird thing here is that they are ALWAYS a bit lower than the ones that the RB system informs me. This used not be the case.
ComeOn odds are also quite often lower than informed (according to RB they should be exactly the same as Bethard) but Bethard that uses the same odds compiler has the correct odds, unless they have already changed the odds of course.
(probably you guys are getting the data from the odds compiler and not from the bookies).
