<div><span style="font-family:.AppleSystemUIFont;font-size:16px;"><font>See pp 10-11 from a booklet put out by R Hadar Yehudah Margolin, available at</font></span> <a href="https://www.dafyomi.co.il/lectures/reviis/kuntras-kzayis.pdf"><span style="font-family:.AppleSystemUIFont;font-size:16px;"><font style="color:#157EFB;">www.dafyomi.co.il/lectures/reviis/kuntras-kzayis.pdf</font></span></a><br />

<span style="font-family:.AppleSystemUIFont;font-size:16px;"><font>What we call "Chazon Ish Shiurim" is a mistake. The measures given for the Seder were not intended as iqar hadin, but included a safety margin beyond the largest known shitah.</font></span><br />
<br />
<span style="font-family:.AppleSystemUIFont;font-size:16px;"><font>When it comes to Berakhos, you cannot make a berakhah for nothing. So when the CI says that a kezayis for a berakhah is 1/3 of a contemporary egg, he is pretty sure that is the actual halakhah.</font></span><br />
<br />
<span style="font-family:.AppleSystemUIFont;font-size:16px;"><font>R Chaim Kanievsky is later quoted as saying his uncle's kazayis comes to 30-33 cc (a/ka 30-33 ml, or 1-1.1 floz). R Moshe's Shiur, 31.2 cc (just a shade over 1 floz), is in that range.</font></span><br />
<br />
<span style="font-family:.AppleSystemUIFont;font-size:16px;"><font>As I noticed comparing R Moshe Feinstein's shiurim and the Arukh haShulchan's, the Litvaks who put halachic weight to accepted practice are pretty consistent.</font></span></div>
