Reagent Test Capacity Calculator

I always been a little puzzled by the seemingly inconsistent sizing of reagents in pool test kits, so decided to build a little spreadsheet to make it easy to see how many tests a given quantity of reagent could handle. I would welcome anyone taking a look at it via this link: http://www.4shared.com/file/12449648...alculator.html

You can:
1) Enter your measurement targets for Cl, TA and CH
2) Enter your chosen test resolutions for Cl, TA and CH
3) Enter your reagent quantities
4) Read the number of tests per reagent for pH, Cl, TA, CH and CYA.

This is largely based on Ben's test kit reagent comparison on the Pool Solutions web site and the Taylor K-2006 test kit. Please let me know of any errors you come across.
