LC: PCA Steps and Optimal times for play

I played the 500fpp freeroll at the 1st step the other day and won a couple of these now I'm getting up to the stage where the buy-in of a step is much higher than I usually play, I don't have notes on these players so I don't know who's who except a few randoms.

To optimise my expectation when do you guys think I should play? Obv. on the weekend but particular time? I'm in Australia FWIW.

Also how would they compare in difficulty to the similiar levels in terms of buy-ins to the SNG's?
