It is amazing how little can be just as efffective as quite a bit more.
With a drug of a different class which I use rarely, I was given 10 mg
tablets with the general dosage 3 times a day. Through trial and error
I found about 1 mg once a day, perhaps 3 times a week *when* I need it,
is sufficient to accomplsh what I need. Then I found I could grind the
five sided tablet in a mortar and pestle, since trying to split it was
resulting in more powder than tablet anyway. The only drawback;
sometimes it tastes of too much cumin seed.

Yes, I understand Crestor is effective at 5mg or even 1 mg.   That's why I
would like to determine the physical size of the pills in the different
dosages to see how far one can split.  :)

You may only need a very small dose:

I've been splitting 80 mg. Lipitor into 20 mgs for years.  Saves a lot of
money.

Crestor seems less expensive but I noted at least one webRx says "Crestor
cannot be split."

Is that true?  Why?

Ideally I would buy the 40mg and split to 10 mg or is that not physicaly
possible?  How large are the 20 mg and 40 mg tablets?

Thank you.
