From the link you supplied:

"Self-discharge: Both NiMH and NiCd are affected by reasonably high
self-discharge . The NiCd loses about 10% of its capacity within the
first 24 hours, after which the self-discharge settles to about 10%
per month. The self-discharge of the NiMH is one-and-a-half to two
times higher than that of the NiCd. Selecting hydride materials that
improve hydrogen bonding to reduce self-discharge typically also
decrease the battery capacity."

So it's more like 10% for the FIRST day, then 10% per MONTH
thereafter.

For NiCd that is right, but is also says up there in the section you quote that NiMH
has 1.5 to 2 times higher self-discharge than NiCd so 15-20% the first 24 hours and
15-20% per Month after that.
