I am checking the new segwit feature, but something seems to be wrong.
If I try to send from a segwit address to a segwit address, the fees are higher than normal. I set the fees for example to 80 S/B, and the calculated value will be 111 S/B. With normal transactions this does not happen. Why?
Transaction fees are calculated differently for SegWit transactions. I'm not going to get into all the details, but look up "Block Weight". I presume Armory will receive a UI update in the future to properly reflect this, but there is currently a disconnection between "Satoshis/Byte" and "Satoshis/Effective Byte"
Specifically, you are specifying the actual Satoshi/Byte with your fee, but with the SegWit discount your "effective" fee is the larger value.
