That's a good result.
It would it have been much better if Barnet had won, but 1 point to Hereford is hell a lot better than them getting an away win.
To catch us they now need at least two wins and a draw out their next 3 games- which include Torquay and Crawley. They also need to get a better goal difference than us (we are +9 ahead as of Friday night). It's going to be very difficult for them to catch us now.
Losing without getting hammered at Swindon would as good as an extra point- goal difference is important. We are only +5 ahead of Macclesfield and they have easier fixtures- Crewe, Bradford, Burton (plus Southend who might be stuck in the playoffs by the last game of the season in which case they may put out a weaker team).
