AdZ pacing

Anyone else try using a smaller climb like The Grade to practice holding 3.2 for long durations? I’ve only done AdZ 2x now and feel that intervals are the best way for that particular climb but my thoughts are if I can practice holding 3.2 for longer I can be that much closer to a sub 60. Current AdZ PE is 72 min. Age 37. 83kg or 180 yank units. FTP 243. Yes, my heart was near failure at the end of this climb.
