As long is that is a table footnote and not a note then the wording looks OK.

Note updates:
Page 157, table 34 in reference to physical link rate long-term accuracy:
Please define long-term (how long is 'long').
Delete reference to "long-term" and change note a to the following:
Physical link rate accuracy may be measured at any point in the life of the
product and should be measured using a frequency counter with a minimum
resolution of 100 Hz.
Page 172, table 145 in reference to the values for hold hold hold (top line
of table):
Discussion on this item pointed out that there is really no requirement for
long-term stability and that the long-term aspect isn't something that can be
addressed in the table because the table only applies for a single command
step. The hold/hold/hold case was verified as a valid request and should be
included. The consensus is that the numbers need to stay and a note added to
the effect that sequential hold/hold/holds do not result in a cumulative
New note:
The peak-to-peak voltage and equalization voltage differences between the
initial condition and following any single or consecutive hold/hold/hold
command shall not be greater than the specified range.
