sbepth- if you are still around.
Regarding my raya from the case of rosh hashana to which you wrote “This as I understand it has nothing to with Reb Chaim. If i have ??? if there is a Esrog in a certain place I need to go find out since I might fulfill my mitzvah 100 percent.”
It could be I am a little late but I saw the magen avraham in ???? says that even if the safek shofar is in a place that they only know seder echad (ie they don’t know how to do a teruah) we still say safek deoraysa lchumra. In this case you do not know if you were vadai yotzei. I know it is not as strong as I originally wrote because it is only from a magen avraham and not a gemara. And yes patur, I know that your chiluk still applies here.
