	The actual limit is 63 and comes from the fact that the indents for the ancestors window are formatted with a procedure that accepts maximum of 256 characters. This will be changed to 65,536 characters in the future.		There is no fixed limit to the degree of nesting in the knowledge tree (or in the Ancestor window). Problems show up at unusually high numbers due to unknown bugs. The actual limit is 63 and comes from the fact that the indents are done with three whitepaces for the ancestors window, and are formatted with a procedure that accepts a maximum of 256 characters. This will be changed to 65,536 characters in the future (SM19+).

	40 days.		40 days.

			The value of four weeks is just a rough estimate of the upper limit that might change from version to version (the limit is artificial as perfect recall, in theory, should result in infinite intervals)

			in SuperMemo 16, maximum O-Factor is 20, which means that the maximum optimum interval is 20, but random dispersion may result in much longer intervals. The dispersion factor varies a lot across versions. Also the parameters of the normal distribution behind the dispersion vary. 38 days should be rare, but possible

			==== How long will a trial version of SuperMemo work? ====
			The credit is on the number of operations rather than natural time. There is no time limit. You can use it sparsely for a very long time. How many actions is a different question.
