180 Old Testament questions: almost the 200 marathon. Law through the post-exilic prophets, the final rehearsal.
One hundred and eighty questions come close to 200: 20 short of the top of this series. Use it for the marathon format without going all the way.
Block the day. Filter 180. If it goes well, 200 is the next step.
Almost the whole pool is in play: Law through the post-exilic prophets, with few book gaps.
Anyone who already did 150 or 160 and wants the last rehearsal before 200.
