Here’s the update:
<div style="clear: both; text-align: center;"></div>Trending a little bit better.  I got the Precious Metals output a bit higher, and now Chiral Structures are the rate limiting factor.  This means I’m pulling in an extra 1.4m or so per day on Enriched Uranium sales.  The POCO taxes have taken about 16m in profits at the 10% high sec rate.  That’s not 10%.  That’s an effective tax rate of about 18%.

They get you coming and going!  Interstingly, the tax rates are pegged to old values, with P1s going for 50isk/unit and P2s going for 900isk/unit, and P3s for 7000isk/unit.  This results in interesting tax rate anomolies as shown above.  There are a few errors, as I lumped a few things together in the beginning and I can’t sort the out now.  Stupid March 11.  But the overall tax rate of 18% is correct.  If I had no taxes, I’d be at about 51m in profit 11 days in.

Edit:  My original effective tax chart was poorly formatted.  I updated it.
