Additionally, you need to weigh the shot output and a good starting point for 14g would be 28g out. Get a cheap jeweler scale with .XX accuracy.
Not really, Vario is almost 0 retention or with my flap in chute flipped is 0 retention, definitely not after multiple shots... I could change a setting and next shot and subsequent ones are the same maybe the 1st shot after the change is a bit different once in awhile in my experience.
That said OP might need calibrating

Thanks for the starting point two posts back. I will buy a few more pounds this w/e and stick to one at a time.
FWIW had a Vario for years and when I've recalibrated it's always in the 3 macro range and then micro adjusted to wherever depending on bean/blend. Use a scale that weighs to .1g to figure out your brew ratio, I'd stick around 50% (ex: 18g in 36g out) and then go from there. Stick with same beans till you have it dialed then make note of where you are, that way if you change beans around you'll know what settings to use. I single dosed the Vario so if a shot pulled fast or slow, I adjusted with grinder running, then dosed again... make adjustments with grinder running whether empty hopper or not.
