as said because you have poor brakes on the back and good on the front you might not want as much pressure to the front and give a bit more to the back,

give it ago and see what you think, start with the "abnormal" setup and see what you think play with the bias ect then try it the other way round, as you do have bias pedal box if you find it works better the normal way round then you can always adjust it with the bias so you cant lose
