greening up your lays

Very difficult.
Could you perhaps repeat it please ?

? please explain.

I definitely think you should eat your greens before you lay down at night.

Interesting thread on the subject here:

http://community.betfair.com/general_betting/go/thread/view/94082/27736281/greening-up---does-it-really-pay-long-term

laying angle only on horses, mathematics tells you re-betting your lays at higher price to green up is a long term loser,ive come to that conclusion, common sense.

unless you lay a fav at 1.96 and your perception is its risky lay
IR price moves to 2.96 if you have percieved that as now value then you can switch your position.

my main point was overall just re-betting all your lays at higher odds IR is losing statergy.

Value in, value out ( give or take a few commission benefits if and when value calculations are questionable or marginal.)
