Yes i'd say so, generally speaking, a standard bitter is a lighter version of IPA, less hoppy, normally if bottle or draught about 4.2% up to 6.5% as an average, standard IPA around the 5-8% average, but you get some weaker/stronger bitters and IPA's. IMO, our IPA here with the larger scale brewers is hoppy, but you can tell it's around 5%, a "proper" IPA, with a craft brewery are generally much more strongly hopped, and you can taste it, and 5.5% upwards as the norm.
Saying that, anything over 7.5% is a bit more expensive as thats the government's threshold for higher beer duty they collect from the brewer.
Just as a guide, Ale/IPA/Bitter/Stout is normally around $3 a 500ml bottle (just under a UK pint), or in supermarkets, they generally do 4 for $7.80 or $9.30 (i try not to go for cans!); in a pub though, draught, you're looking at between $5 and $7.00 a pint; clubs well, bring your credit card! and generally it's generic crappy lager
If i could get this bloody signature thing to work it would be a very pretty picture
