We make some educated guesses for the extrapolations of typical
soft-inclusive (minimum-bias, pileup, underlying-event) observables to
proton-proton collisions at center-of-mass energies in the range 13 - 100 TeV.
The numbers should be interpreted with (at least) a 10% uncertainty.Comment: 5 pages. Update (v2) adds numbers for 13 TeV and corrects bug in UE
