Tasks for Garrett when he is in Beijing

• Re: Starspot evolutionary model comparison possibility: "... crude estimate based off my models by linearly extrapolating forward from one of my less spotted models."

• Re: Despite being only an example of one, can we infer that LkCa 4 has undergone diminished convection efficiency, leading to an underestimate of its age? (A: lots of modelling possibilities here)

• Re: "Contraction rate would be slower"

  "While this is true, the dominant impact on the age is simply the shift in temperature, with causes the un-cautious interpreter to use an evolutionary track of the wrong mass. If you want some text about how this might work, I'd be happy to provide it."

Yes, provide this

That last bullet point might still be open
