Models targeted at DJs will have variable speed adjustment on the front panel to allow beat-matching. Some turntables for home listening will have 2 or 3 speeds with a fine adjustment for calibration. Rates will be off due to manufacturing tolerance or mechanical wear (i.e. a loose belt slipping on a motor). Most people don't worry about it. It doesn't really vary album-to-album, unless you have some ridiculously heavy records that slow the motor.
