I wasn't ignoring you Whirly, I just hadn't read this thread through.
Doing more hours doesn't necessarily make you a better pilot. If you're doing it wrong then doing it wrong more often is hardly an improvement.
On the other hand the biennial flight with an instructor might well lead to bad habits being picked up and corrected.

It's not 12 hours and an LPC, it's 12 hours OR an LPC (which has just been upgraded to include Nav)
While the rules are there and have to be obeyed people should not be fixated on them. If adherence to the rules does not prohibit you from flying that is not the same thing as saying that you are OK to fly. Use your judgement, if you are not comfortable DON'T DO IT. (please excuse shouting).
