A 10S pack is capable of charging to 43.5 volts. The rules say the legal limit is 42.99 volts. Capacity increases on the 5100 10S in the neighborhood of 500 mAh with the added volt. That's consistent and quantifiable on my Power Lab chargers. So the added capacity is significant.

So I have labels for our packs that say they are HV. I also have labels laying around that don't say HV. Albeit they say Gator Power packs instead of Power Unlimited HV.
