We're getting more consistent feed back, from people following the process as written. That makes it possible to more accurately evaluate how well it's working.

One of the big problems all of us have, is that WE don't have most of the problems users come here with -- we learned to avoid them, long ago. So, we have to rely on user feedback for more information. But pool owners are so used to failure with pool products and processes that they don't always tell us when something we've recommended doesn't work as we expect.

I'm hoping the new Pool Chart + the Pool Log (customized dosing calculator and test record for subscribers) will allow us to improve our advice a LOT, over the next year. It's probably already the best available, but it's a long way from perfect.
