Thanks to your explanation I finally understood how it works.I was wondering why does the value change so drasticly after slight changes in the price and sometimes doesnt.I was also confused what happens with reward value according to Steem price.Because sometimes pirce fell and I still got the same/bigger reward value.Great informative post.
BTW Surprisingly this time the math was easy and simple :) (I know you made an easy example not including other factors)
