Those are the nodes which allows incoming connection. It's methodology gives an inaccurate sampling of the actual node count as it doesn't take into account the nodes that doesn't allow incoming connection.

Based on the estimate and how much I've managed to sync over the last three days.

More importantly when I added a bunch of Nodes manually the estimate dropped to 40 hours. and speed of sync dropped dramatically.

Adding nodes may not always help. Some nodes are crawlers which will not help in your synchronization and would infact slow it down. The synchronization estimate will fluctuate quite wildly, when it hits a patch closer to the present day, the synchronization would slow down a lot as the more recent blocks contains much more transactions to be validated. Increasing the dbcache will help quite a lot.

Depending on your SSD model, some QLC SSDs will slow down significantly after the cache gets filled.
