Had another look and got a better setup with levels: [1, 4.25, 6.75, 8.25, 11.5, 14.5, 16.0, 16.5, 20.0],
rather than the default levels: [1, 3.5, 5, 8.25, 11.5, 14.5, 16.0, 16.5, 20.0],
Also have a better understanding of levels.. which basically work alongside geohash and matching substring of chars.
(with overriding limits of google map zoom 1 -> 19 and only 12 levels available)
I think some of the issue here is that geohash inherently limits proximity due to 12chars when encoded...
km
1 ± 2500
2 ± 630
3 ± 78
4 ± 20
5 ± 2.4
6 ± 0.61
7 ± 0.076
8 ± 0.019
9 ± 0.0024
10 ± 0.00060
11 ± 0.000074
So a little arbitrary when trying to match to zoom levels?

Hello Mike. Indeed the values I use as default are completely arbitrary and based on few tests. Is the rendering OK now with your new values ? May be I could update the default ones with yours.

feel free, seems to work better for our needs.
FYI some user testing feedback for you
I am having to explain why the difference from the previous incarnation which was based on Fluster.
Geohash seems much more performant, but some users are a little unnerved by the clustering changing when panning viewport, as opposed to fluster where clusters remain constant when panning.

I have trouble understanding exactly what you mean by "panning" ? You have a use-case where your map view size is changing ?

panning the map around (dragging without zoom)
