I think there are some minor discrepancies between how your calculator calculates power and how the EH system calculates power. Your calculator says I should be at 112, but I'm actually at 113. It's probably caused by the system using exact values for days instead of whole numbers.
Meaning according to the system, I've been registered for 388.99 days instead of 388 days (rounded down.)
I'm also fairly convinced the system uses 365.25 days in a year instead of 365 given the timing of my power increase (maybe even 365.242199, the exact amount.)
You would be wrong. The system uses 73 days, or to be more precise 6307200 seconds. Also, to quote the technical Karma & Power section of my help file:

Also, the server actually calculates the number of seconds you have been registered and convert it to days. Since most of us do not know the exact time we registered, the calculator only generalizes the days. This may cause some slight rounding issues under certain circumstances.
Also, please keep in mind Time Zones as well.
