N6BV makes a good case that Es on 10m-20m was a factor in the extremely high
number of EU QSOs (ITU Zone 28/29) experienced by the competitors near
Moscow at the WRTC in 2010.  He does this by comparing VOACAP predictions
using F2 only versus F2 plus Es.

"How Important was “Short Skip” Es on 20-10 Meters in WRTC 2010?"

"R33M made 1,080 (47%) of their non-ground-wave QSOs in Zones 28 and 29 on
20/15/10 meters. This strongly suggests that short-skip Es was present on
the higher bands!"
