double if you are playing the same quailty of players at $2/$4 as you are at £1/£2 then you would save yourself alot of money
your winnings would remain at £3000 but you would save yourself about £600 in rake as your rake would be cappped at $1800 instead of £1800 thus meaning your ratio of win to rake would be affect greatly in your favour
lol I like the new name.
Unfortunately it doesn't work that way because a large % of pots don't break the rake ceiling i.e. pot 30 gets raked by the same % in both currencies. Although 2/4 being a slightly larger game would have more pots breaking the ceiling. I do agree though that it would be preferable to play the same players at an equivalent $ game, but that doesn't happen.
It's still a good idea to lower the rake ceiling from $5 to $3, you will save a huge amount.
And you wouldnt notice a diffrence in standard.
