Yep! This was mostly because of the patch released by the Steemit Inc team a day after Hard Fork 20 went live. 

According to their blog post from 3 days ago, they forgave/reset all RC Debts (accounts with negative RCs) and increase RC allocation ten-fold. If an account has an RC of 1 Million before the patch after the patch that account will now have 10 million RC, which eventually made almost all accounts RC's miraculously up by 100%.

As to my opinions on the Hard Fork, I actually made a blog post all about it and can be read here: https://steemit.com/nathanielhammel/@jlordc/pknypnc75

But the gist of it is mostly positive, the update will most likely solve the spam issue on the blockchain and will bring Steem to greater heights in the months to come but the way it was implemented and released to the general public is very disastrous and disappointing.
