So, I did some follow up on how accurate (or inaccurate) the calculator performed this week (even though there were a few days of crappy data last week)...
I'm pretty pleased overall, for example here's the LTC results:
Calculator Estimate:
0.0213694113 LTC / 7 days / 1 ASIC Share
Actual Total:
0.02148952 LTC / 7 days / 1 ASIC Share
Now, when it comes to the other coins, there's a little more variance in numbers (I suppose attributed to the larger swings in diff throughout the day... esp. w/ DRK, which can have some pretty radical swings throughout the day).
So, i've made a couple minor tweaks to the overall formula (thanks to a couple of suggestions) and have bumped up the sampling rate to see what a full week of regular (meaning me not screwing up something and having to wipe out stuff in the database) results brings.
Of course, I also couldn't resist adding a new shiny thing and have added a Historical Earnings chart... while it's kind of useless right now since the data range is so small, the goal is to just let you, at a glance, see how stable (in terms of BTC) the coins you are mining are...
