OP, thanks for sharing what you found through your own dyno test. I for one appreciated it.
Every once in a while there are little things that make me go hmmm, and it was nice to have someone confirm and share an experience.
Ignore the rest of the folks here that have nothing better to do than make you feel bad for sharing.
