Pre work up yields describe the reaction and its product distribution. Its the only thing for the physical organic chemist.
Post work up yields describe a preparative method. It is what synthetic organic chemists like to know.

The first require analysis (HPLC, NMR, GC, TLC, many more) of the reaction mixture.
The second is only meaningful when the purity is also stated.

To exaggerate the yield, unfortunately, is not a reliable method for impressing the supervisor...

yours
