I have no hopes of being a world class 1000 yd bench rest shooter, so why would I worry about super charge weight accuracy?
If I did, I would just wait for a V9 that auto trickles and seats bullets, hands free.
This thread is really about this scale, not about whether you need it or not.
The options appear to be either upgrading to a V4, or a a tuned beam

There are so many that complain about digital scales drifting often attributed to electrical and static.
(search forum for static). Thumbtacks in your bare feet might help ( ouch). Power conditioners, antistatic mats, and Faraday shields, drive up costs. This scale is no where near the price of a great scale. Just a good one. I did pick a different brand, about the same cost but the 4th digit helps with weighing things other than for just reloading.
Creedmoor didn't go off the deep end with resolution, just maybe a nice stable scale accurate enough to not matter to MANY shooters. I see it in the Good Enough category reading to 0.01 grain. Good enough that error properly using it would be close to insignificant. I dont see how you could miss by more than a few counts.
The grain native mode is nice for those math challenged that don't understand units of measurement and use a milligram scale in grain mode even though a milligram is a little less than 0.02 grains which seems to be good enough for a lot of shooters.
