This thread been been dominated by the “high watt/kg” end of the spectrum. Remember that Nate posted some great stats about average watt/kg here: The Bell curve of cylists - how fast are the average TR users? - #124 by Nate_Pearson
I’m curious what the folks on the left side of the bell curve are doing? In my case: Got back on the bike in August after several years of putting on weight and not cycling. Did ~100 hours of unstructured riding (mostly commuting) over 3 months, then started structured training at the end of November. Was 95kg and 214 watts FTP (2.25 watts/kg) at the start of the structured training.
Goal for 2019 is to get over 3 watt/kg and make it to the right side of the bell curve :-). I can get almost all the way there on the “kg” side of the equation, so I think 3.0 watts/kg is reasonable.
