\caption{\label{tab4}Summary of F6-F9, G and K observations derived in this work vs.
scaled predictions derived from XCOUNT, for each 
range of age. For 8~stars of our sample of late-F to G and K~stars we did not measure lithium EWs (upper limits) due to the low {\it S/N} ratio of their spectra and/or high rotation.}
