No, they are not.
Years ago I haughtily decided not to track the Junior games because in the beginning they were intended to be a more...introductory setting.
I agree this changed over the course of time, but by now there is no way I could go back and aggregate all that information. I don't have time to undertake such a herculean task. I hope somebody else might be able to do so as I think it is an important piece of Downs history.
Embarassingly for my role as Lord High Scorekeeper...I couldn't hope to track down my own personal stats as at this point I have no idea what games I played in.
