In parshat Emor we are told to bring the sacrifice of two loaves and two lambs on the second day of Passover. The loaves are waived. Rashi cryptically quotes a talmud in Menachos stating that we wave the Omer to restrain the bad winds and the bad rain. Presumably this is to ensure successful harvesting of crops. Rashi leaves out the best part. The Talmud at 62A states that the waiving of the Omer demonstrates that even a partial execution of a mitva grants merit because the “waving of the omer” is the “residual” part of the mitzva.”

The Shikkerdovid would like to share something ironic. The Mitzva of counting the omer is famous for the scholarly debate as to whether it is one mitza or separate mitzvot. The implication for the one big mitzva is that if one misses one day, the full count is lost. This stands in start contrast to the above idea that partial credit is given. How do we understand these two competing ideas? Maybe this Talmudic idea of credit for partial execution should sway the day. Maybe this is why Rashi did not fully quote the entire thought from Menachot and just cited the page?
