looks like there is still some missunderstanding (or even bug?) with the mana stuff.
One example:
API returns
'current_mana': 109210831230,
'estimated_mana': 126474130595,
'estimated_max': 222766110968,
Some hours ago beem-library as well as steemd returned
100/estimated_mana * current_mana = 49%
and steemworld as well as steemnow returned
100/estimated_max * currentmana = 86%
now things changed - even more strange:
steemd/beem return a 56%
steemworld and steemnow return 100%
