3 good results in a row - deserved?

I don't get to go to the Shrewsbury matches any more and wondered whether Shrewsbury had really hit some good form over the last 3 games (Darlington, Carlisle & Peterborough) or whether I can expect us to start losing again. Anyone seen these and other recent games that could comment?

Just from following the reports on the web, Peters seems to be quite active at bringing new players in but especially at letting others go - is this the cause for the mini-revival?
