I tried this a while back and posted results in this thread. Short version is that the play at low stakes is generally much worse and you can be very successful there with a straightforward, simplified value-betting strategy.
With respect to the super-micros at 1/2 and 2/4, your observations seem spot on to me. Again these levels are very easy to beat - wait for something like 88+ / AJ+ and then just shove preflop - you’ll get plenty of callers. Variance will get you in the short run but it’s very easy to win multiple buyins quickly.
