We can e.g. make the recommendation that simulations runs are repeated (to N=5 or better) until the type A relative standard uncertainty from repeated runs is smaller than or equal to 1.0% (or some other useful level)

Full uncertainty estimates from framework model is more complicated, we can use current best estimates for e.g. average deviations between simulated and measured results, or section the field into "iso-uncertainty areas"

A reasonable choice could also be based on the 75% quartile value of the relative deviations between measured and simulated air kerma rates from nanoDots from the article, which is a 8.5% (this is the current methodology in the article for relative uncertainties on absorbed dose rates - the uncertainty in going from air kerma to absorbed dose due to Monte Carlo methods is expected to be negligible in this case)
