No. I'd do it upon receiving notice that a faulty package was fixed.
Or that a newer than installed package is needed by a (previously
updated) package *I* need.
Installing updates puts you in a tester role. Before performing an
update I'd try to read its description.

Old packages can be removed, new packages can be integrated, package
ingredients can be moved to other (faulty) places. The latter
happened for example in XeTeX. Those who updated XeTeX from SVN have
in TL2007 still an obsolete XeTeX url.sty; XeTeX-reference.pdf,
xunicode.sty, and xltxtra.sty will exist twice – who can guarantee
that the last installed version is found and used?
Anyway, it can happen that with an improved tlmgr, than can add and
delete, a TeX Live <year> release will be just a snapshot from an
No project was ever completed on time and within budget.
