SC 2020 test puzzle: first output of billion cycle monster
70.8M cycles elapsed before recording started.
Video switches to slower speed at 1:30, the first 90 seconds are to give a picture of the input stream preceding this to establish position in the 12bag randomizer, as well as show how the accumulator under the cursor, gets reset a lot preventing it from reaching 72 where there is a Krypton output and leading to this insane cycle count.
