In my cars I usually would double clutch the downshifts as the upshifts didn't seem to help that much.
It seems to be easier for the synchros to bring the clutch/input shaft RPM down than up. When double clutch downshifting or revving to get back into gear, it seems like slightly overshooting the RPM and letting the synchros bring it down a little works better than slightly underrevving and forcing the synchros to bring the clutch/input shaft RPM up.

If I had to guess why, I'd say because the synchros have friction and oil drag on their side bringing the RPM down while they are fighting friction and oil drag to bring RPM up.
