For members with up to 25 Steem Power(SP), you can earn up to 25 Shadow Rank (SR). If you were above that we apologize but the new RC/HF20 upgrade has caused a lot of changes and we have to adapt as well.
Members over 25 SP and under 100 SP can earn up to 1/2 their total SP in addition to the base 25 SR. For example, a member with 50 SP may earn their base 25 SR + FLOOR(50 SP) = 37 SR max. A user with 100 SP can earn up to 25 + 50 SR or 75 SR total. Powering up above 100 allows the old system of SR to kick in and ensure you get even more!
