Been looking at the safest way to extract my free £25 bet (not going to risk just clicking withdraw as i fear they'll just take it back somehow) and settled on number of subs again (i know, i'm a maniac). Anyway, it seems like 0-3 subs is so unlikely as to be barely worth considering leaving 4-5 and 6 subs as the very likely outcomes.
Betfair odds:
4-5 subs = 2.4
6 subs = 1.89
Am i right in thinking that if i put £10 on 4-5 subs and £12 on 6 subs i would be up if either of those won? e.g..
4-5 subs = win £14 but lose £12 stake on the 6 sub bet.
6 subs = win £10.68 but lose £10 stake on the other bet
Have i gone wrong somewhere?
