Debug Mode: units?

when using debug mode (ctrl-F9), in what units are expressed the values ? and what is the maximum ?

for instance, is 50 a high value (for a subpatch).
Thanks (i haven’t found anything in the search)

I was wandering about this as well. Someone must know surely?

late answer:
gregsn told me once something like that he himself can’t tell exactly the units…
al least it is useful to see the relative performance needs of the nodes.
