I have tied all the suggested solutions ?clear ports and update software) but Garmin 530 consistently under-reads elevation gain. Today, reported number was less than 50% of verified elevation gain.

4400395 I would suggest reaching to your local support team to investigate this report. Support link
Looks like Garmin support beat me to it ;) In addition to suggesting you contact them, I was going to say that my understanding is that the elevation data comes from a barometric altimeter, which can drift because of changes in air temperature and pressure (weather) and the amount of time. 1300 m still sounds like a lot though! (I think I've seen 100 m or so at most.) If the device does this regularly though then It may suggest a problem with it. In either case, contacting Garmin support is probably best.
