"Compressed" is a term I use to describe there being less overs but with the anomally of having the same number of wickets. A decrease in time/overs increases risky behaviour of batsmen and the agression/conservatism of the field/bowler.
Thanks for the clarification and I am assuming that if you keep all the factors (time/overs) consistent with the real thing, i.e. 30 overs in a session in a 5 day Test, you will get results similar to real-life Tests.
