Dendrochronology cross dating

How many "spacer" values are needed to shim ring width sequences in order to "help" a correlation between two sets?As far as assumptions go, I couldn't really find much about this. Wdanwatts , (UTC)Surely this is all depends on what's being counted and how. Without knowing that, it's not possible to say that years with '0' values are included to aid comparison and correlation.

After reading, I understand better the concept of tree rings and some of the finer details that complicate the issue (such as alternating poor/favorable conditions and "missing rings"), but I don't understand all of the applications to understanding past climates. Please feel free to edit the article to make these points clear.
The sources used in the article are mostly peer-reviewed and seem relevant for the most part. Jclerman (talk) , 9 November 2008 (UTC) How does dendrochronolgy correlate with C14 dating?
Thus a ring may be missing from one core sample, but present in a second core sample from the same tree at a different point on the trunk's circumference.
Second, very rarely an exceptionally slow-growing tree will not lay down a ring at all on its trunk in a poor (cold, dry) year; this can be detected by comparison with the rings of neighbouring, faster-growing trees which do show a narrow ring for the bad year in question, or by comparison with branches higher in the crown of the same tree, where the ring will be produced.
