I'm pretty sure there's no FA rule about consecutive home games. More likely it's a general parameter our league give the fixture compiler.
Had a look back through Ashton's past seasons, in 2007-08 we played three successive home games on three Saturdays in February/March, but there may have been away games in midweek postponed due to weather? In 2005-06 we played at home oin midweek and the next two Saturdays (Sep/Oct) and then a home midweeker followed by three Saturday games at home (Mar/Apr). 2004-05, four home games in 10 days (Mar/Apr) - although that was Conference North.
