If you watch @zephyr1’s video in slo-mo you can see the Hams start at 1570k. You add 47.28k from the first farm and the counter scrolls to 1618k. The second farm adds 47.286k and the counter jumps to 1665k. The third farm adds 75.614k and the counter scrolls to 1741k.
All the Hams are there, but visually sometimes the counter scrolls and sometimes it jumps.
