I've interpreted this algorithmically as (excuse off-by-one errors):
1) Rank-order an author's papers by total cites to each.
2) Count from the highest-cited paper to the lowest, stopping if your
count is greater than the total cites to the next paper.
Hence an author's h-index will never be a higher value than their total
number of papers.
As an exercise I've run this algorithm over Citebase
(http://www.citebase.org/) for several thousand *names*:
(aid is an internal identifier)
My 2c is the h-index benefits consistency - 'outlier' authors with few,
high impact papers or many, low-impact papers are suppressed. Given it
is an index whose range is limited to total number of papers (a few
hundred for prolific authors), I imagine this is applicable more to
authors at the end rather than beginning of careers.
(It would be interesting to apply the h-index to larger bodies -
institutions or research groups.)
All the best,
