Statistically, you'd have more chance of connecting if you try to connect once every 120 seconds, than once every 120 to 160 seconds (averaging 140 seconds difference per attempt).

It will improve your chances on few occassions, but on average your connection chances will be lessened.

Basically, how can you say that less connection attempts will result in a higher connection rate?
