Why does it take 4 days of not logging to deplete the daily bonus wheel 15 places?

I was away from CC for 4 days, unable to log in while on vacation. My wheel dropped from full to half. So, you would think that 13 days would refill? No. I am still at 27. What a ripoff. I am at level 10,000 +. Buy ads cycle at least twice between every game even though I purchased ad free.
