Does adding PEC to your mount improve guiding?

In this video, with the help of Astrobloke, we go over PEC Periodic Error Correction and how adding it to your mount will improve your guiding. Additionally we go over permanently saving your PEC curve to your mount.

How to apply a PEC (Periodic Error Correction to your mount) Start by recording a PEC curve. Recommend setting a minimum of 5 worm cycles. This will, once made, start to correct the errors while guiding. You can tick autopec and every time you start up this curve will automatically start with your guiding. BE AWARE that if you do not park your mount before shutting down this curve will be lost.

Here are the steps to save the curve permanently into your mount so it will not be lost. This can be done anytime even during the day.
Start your mount and make sure it is tracking as sidereal + Pec, fully open eqmod and on the far right is the development area. Tick record PPEC.
The red light on your mount should start to flash.
The mount is now syncing the worm drive with the curve you have recorded. Once synced the curve will be recorded into the mounts motors, The flashing light will change to 2 flashes and a pause.
When this has finished the PEC curve is permanently saved into the mounts motors. Start your system again making sure autopec is unticked and tick Enable PPEC. if you press refresh it will report if it is on or off.
Another way of confirming the PEC is active is the light on your mount will now flash 3 times and then pause. You now have PPEC saved into your mounts motors and hopefully a much improved guiding status for your mount.
