Instead of averaging the four closest isochrones, average the metallicity first and the age second:

Given a (z*, loga*)
Find the loga value in the isochrones closest to loga*: loga0
Average the two loga0 isochrones with: z1 < z* < z2
Now we have a new isochrone with (z*, loga0)
Find the z value closest to z*: z0
Average the two z0 isochrones with: loga1 < loga* < loga2
Now we have a new isochrone with (z0, loga*)
Average the isochrones (z*, loga0) and (z0, loga*) --> (z*, loga*)
