With those thick Crown Heights matzos, it takes 20 minutes to eat a k'zayis of matza!

Whos says Crown Heights matzohs were thick then...

Anyway they are nothing compared to Kfar Chabad Matzohs.

By the way the kezayis of matzoh has to be eaten in "Kdei Achilas Pras" less then 6 minutes.

If you insist on addressing the issue seriously then here goes:

The estimates range from 2 to 9 minutes.

IMO, the various books and guides on the issue are lacking in that they do not take into account that when you enlarge the size of a k'zayis, (based on the issues introduced by the Nodah B'Yehudah and Chazon Ish who doubled the k'zayis) the time should be doubled as well.

Another issue that needs to be taken into account, but which I have not seen discussed anywhere, is that there is an obvious difference in how long it takes to eat something when it is soft as opposed to when it is a hard thick (yet un-crisp) cracker. One round matzah would take far less time to eat were it soft like an aish-tanour-type pita or mexican style fajita than its current hard state.

L'Maaseh I ate plenty of matza at the sedarim, with no time wasted, but 2 minutes for a 6*7 inch piece (R'Moshe Feinstein's shiur) is somewhat unrealistic.

Is there an official Chabad shiur for the amount considered a k'zayis?

The Rebbe in a Haoroh in Sefer Minhogim p. 45 writes that we should be Choishesh for the Shmuah from Reb Hillel Paritcher in the name of the Tzemach Tzedek that it's 'no less than 3 minutes and no more than 7 minutes' and practice 3 minutes.

For a Kzayis bread of Mezonos(which obviously includes Matzo) the Shiur is 27 grams.
For fruit, meat, fish, and anything heavier than water, it's 30 grams. One must eat extra to accomodate for the food stuck between their teeth(and gums). This is the Shitoh of R. Avrohom Chaim Noeh Za"l.

It says clearly that regarding Tisha-beOv that's the Shiur. When it comes to fasting we're Machmir to go with MORE minutes(because there, it's a Chumroh). But in everything else, like Matzoh, Brocho Acharona, and the like, we're Machmir to go with LESS minutes.

27 Grams is the shiur of a kezayis b'nefach (in weight). In your average shmura matza it is slightly less than 1/2 a matza, as most hand matzas average somewhere about 8 matzos per pound.

But, the shiur of a kezayis matza we need at the seder is a shiur b'nefach (a kezayis in volume) which is considerably smaller.

Since determining the volume of a kezayis in matza is very difficult, as one has to account for the air pockets between all the crushed matza, it is difficult to come to an exact amount.

In Piskei teshuvois he bring that there was someone who calclulated the exact volume using a vaccum, and the conclusion is that a kezayis is the size of a 1/4 of the average matza. Some hold that even 1/6 of a matza is a kezayis, (see hiskashrus, he writes a 1/7 but his cheshboin of gram shtims more for something around a 1/6).

L'maaseh a 1/3 of a matza is for sure a kezayis l'chol hadei'ois
