Going to try the theory of 2 cuts a week
Right, I want my lawn to thicken up, and try and get rid of the weeds in it. So, I've just spread my fertiliser and moss killer, (well at start of week day before it's piddled down) and now I'm going to religously cut the lawn twice a week. I shall use lawn fertiliser every 6 weeks and see whether the increased cutting really does encourage the grass. I shall report back throughout the season.
