What exactly is meant by 10 simulations on community plans

New to the community, was exploring community plans, needed to ask what exactly is meant by 10 free simulations? Is it a lifetime limit, or yearly or monthly?

I think it is a lifetime limit for the account. One can though do more simulations, but the numerical results will not be downladable/accessable. During the simulation one can though see/download the intermediate results (for instance of each iteration).
