at 4 weekly i often heard "is it that time already,mmm,you sure you arent early "etc so i slid mine to 6 weekly and no moans. the only downside is if you are later than 7 the windows are hard work
one woman collared me yesterday,id let her be 12weekly but she is narked that she really wants 3 monthly ,wants me to arrive in the last week of the month, but i couldnt see how to write that in George. so she said, ok make it 11weekly !
