Thanks. That's a nice chart and seems roughly consistent with the table at the end of this link. The half-life (50% loss of concentration) of 12% bleach at 90ºF would be around 80 days or 11.4 weeks which is a little better than the projected 9 weeks in the chart, but the Odyssey product is supposed to be of high-quality mostly free of metal ions so that it lasts longer.
