(I) can't get maximum zoom scaling working
I have searched for 3 hours in vain how to get max zoom scaling to work.
I'm using this server (Wallonia, South Belgium, buildings layer only for the show))
wms[15]:http://geoservices.wallonie.be/arcgis/services/TOPOGRAPHIE/PICC/MapServer/WmsServer?&SERVICE=WMS&VERSION=1.1.1&FORMAT=image/png8&TRANSPARENT=TRUE&REQUEST=GetMap&STYLES=&SRS={proj}&WIDTH={width}&HEIGHT={height}&BBOX={bbox}&LAYERS=1
As I zoom in, tiles get blank (transparent). Frustratingly, there's a scaled tiles flash before it gets overwritten.
I'm fortunate enough to have heard of the max zoom [15] in the URL here above.
I suppose the effect is to scale the tiles, Help/Preferences/Imagery does not mention it.
I would like to know which one to use, at which zoom level the tiles turn off.
But every article I read spoke of zoom levels in meters, a notion unknown to my server.
I supposed that working up from an unreasonable value would determine the value, but ... no scaling.
I saw a ticket making a patch for utilsplugin Jumpto specifying true zoom level.
I've got utilsplugin2 installed, Jumpto has no sign of zoom other than meters and Help/View Jumpto is silent about zoom.

How do I maximum zoom scaling work?
What are the obscure answers to these questions?
I'll hold the door open for the followers (add a few sentences to HELP).
