I'm looking forward to sakamvari's reply after he sees the screenshots (ha ha).
In the meantime, however, you might simply accept that this happens and know that it's not just you. The meter is useful and shouldn't be removed simply because it isn't perfectly accurate. Post-game analysis is inaccurate in the same way (presumably using the same best words), but I don't think anyone would want to get rid of that for this reason.
