Is Asian handicap having problems in Bet365

I have been betting in bet365 in the most betting categories Asian handicap is the most problematic.
Maybe is because the randomness of some low leagues, I have make a strategy that could be useful:

Low leagues
-Handicap 0.0 only local.
-Handicap +1 away and local
Handicap +0,25 0,5 si es local if is pay 1.75

Let us know how it goes.
Of course you need many more bets to draw a conclusion.
As an example I have not done anything “special” for the AH bets on B365 and my yield is 2.6% after more than 7000 bets.
