The pond now has about a quarter of its surface are covered with frogspawn. I have no idea what depth it goes to but it is certainly not restricted to one layer.
There is still no sign of the frogs during the day. The ones last year had no such fear of people or the camera.

EDIT -- I forgot to say that I got the slideshow making programme up and running and have posted an AV show of the Pepper Dragon HERE.
