What is the ink on the bevel showing, are you reaching the edge?

So what is the grind of the razor?

If the razor has a full hollow grind, and you are using too much pressure, you could be lifting the edge off the stone.

There is an unusual pattern at the top of the bevel, away from the edge, where it could act as a fulcrum and raise the bevel off the stone.
Ink will tell you how much pressure you need to get the bevel flat on the hone and if you are reaching the edge.

An extra layer of tape will correct for a worn spine and hone more of the edge.
