Has any reputable organization ever put forth a possible value for fl (the fraction of life-supporting planets that develop life) in Drake's Equation? I can't find a single one, other than Drake's original value, which is 1 (i.e., life will always emerge from a Goldilocks planet containing water).

I see people like Neil deGrasse Tyson claiming life on other planets is pretty much guaranteed, which would suggest he has a value for fl in mind. If so, I'd like to see what it is.
