Not sure decimals is that good for on course bookmakers

when i go racing say a horse is 6/4, u bet in accordance to get notes back, so £40 win, or at 4/7 £70 or £140 win.

But at like 2.52 or 1.52 as it is there today you get a load of coppers.

Whereas at home on betfair that doesnt matter.

Anyone ever thought of this?
