It's the first time I subbed 40 s without 1-key finesse. Though, I couldn't do it with 1 preview and completely random piece order. This video is a part of my *requirements of fast paced Tetris* studies.
Bag randomizer, 2 previews 38.45 s (2.60 pps)
Bag randomizer, 1 preview 41.81 s (2.44 pps)
Memoryless rand., 2 previews 40.73 s (2.50 pps)
Memoryless rand., 1 preview 41.83 s (2.39 pps)
From my experience the number of previews is a more decisive factor than the randomizer. With 2 previews, I could maintain a better flow, i.e. in average smaller pauses between dropping a piece and moving the next one. With completely random piece order, I had to stop more often, because I didn't see a good spot for the current piece fast enough.

edit1: way more elegant solution to last riddle (as suggested by David Sili): [ ( move + rotate + move ) x 4 + rotate ] x 4 , rotation direction doesnt matter in both cases
edit2: Apparently, you can change how often a loop is repeated. With it, you can solve last riddle with just 4 elements (as suggested by Andrey Rybak): ( move x 3 + rotate ) x 13, thats the same path as in my solution but way less elements
I am no kid but I thought the doodle looked cool. The solution to the last puzzle looks kinda weird. The goal is to minimize the number of used elements (4 x loop just counts as 1), not the number of steps the bunny makes.
