Summary:

Can there be a robust estimate of tau Ceti 'f' albedo ??
tau Ceti 'f' is an *interesting* planet, on habitable zone's outer border-line around a mostly placid, mid-K star, its Sine(i) mass highly sensitive to orbital plane alignment.

IIRC, current estimates are based on the big asteroid belt's ~35º inclination to line-of-sight. With necessary proviso that estimate may be up-ended if belt is skew, eg due one or more planets' 'Long Tack' per 'Nice Model'...

Given such potential 'gotchas', and pending actual optical resolution, can there be a robust estimate of tau Ceti 'f' albedo ??

Do we have more than just the radial velocity? If not, I don't see where an albedo estimate would come from.

Planetary atmospheric modelling / monte-carlo simulation ??

With just the very approximate mass and distance to the star you can't do much. There is nothing a robust estimate could be based on.
