"Fine margins" is a cliche but games are more often than not won or lost by the odd goal whilst those lost by a wider margin often turn on a key incident. Generally though, you can work out very early in the season if you've got enough to make those fine margins mostly count in your favour or not.
Posh finished 4th last season in L1 as top scorers, so factoring in the performance of the 1st team game you'd have to say the 0-1 was encouraging, if pre-season games do matter. If they do matter then the positives are offset by a very bad result at Boston. Not beating a York side that barely avoided a return to tier 6 North wasn't a great look either. Beating Wycombe is the best pre-season result, albeit in non-matchday conditions (BCD).
