So maybe there is no absolute figure, just one that is relevant to your segment and what it can sustain. On ours, we regularly get <50M on a 152M tier in the evenings and have done for the last 3 yrs or so .. Have said that, there is no way VM are going to zone download/upload limits so it is a moot point any way.
I don't consider us as "heavy users" plus we have the download constraint in the evenings and weekends. Here's our usage for the last few months:
