[Avodah] Safeiq Sefirah

[Micha Berger]

My 13 yr old boys and I were learning KSA yesterday, and one of them
asked the following question:

According to the KSA, if you are unsure if you counted yesterday or not,
you can continue counting with a berakhah. Chasing it down a little, the
reasoning seems to be sefeiq sefeiqa -- safeiq whether omer is one
mitzvah or many, and even if one mitzvah, safeiq wehther or not you
broke the chain.

So, Zack asked: We know from "mashiv haruach" the rule that if you
haven't been saying something 30 days I should assume I didn't say it.
To the extent that we override safeiq berakhos lehaqeil and require
repeating.

So why do we say there is a S"S, the second safeiq has a chazaqah -- day
1 to 30, assume it was missed, day 31 onward, assume it wasn't. And
therefore if someone isn't sure if he counted on day 15, why doesn't he
have to skip the berakhah?

I might ammend his question. It's not 30 days but 90 repetitions. And
therefore the entire omer would fall under the question.

Tir'u baTov!
