I've written several postings here over the years concerning timers. If you've read them, then you have my recommendations.
Nothing about NSR is cast in cement. Guidelines are not rules or regulations that must be followed. The aim here is not to restrict freedom. The aim is to give useful, helpful advice.
Anyone who feels that a guideline is wrong for them is welcome to reject or not follow it. I do ask one thing in return, a small favor. I ask that you post your experiences here after a few weeks of not following the guideline. That way, we can all learn from your experience. A guideline can be overturned, adjusted, or confirmed. This will be helpful to future clients.
