If you want to unclutter output a little, you can wipe the 5536 MSRs
from the file after the first run. msrtool only considers the MSRs
that are explicitly listed in the input file when run with -d.

(Another alternative is to list relevant MSRs in the file before the
first run and run with -s rather than -l -s. The former reads and
outputs values only for listed MSRs, the latter reads all known MSRs
but has the benefit that no file needs to be created beforehand.)
