The thing is with people's criticism of NSM, is they never really lay out something better when challenged. Poor Magness, but even he didn't really have an answer to why would he change anything when the athlete was still improving? He couldn't seem to remove the concept that hobby joggers might never really get to the point they need true intensity and default mode was to just to back to what he knows.
If you think there is a better method out there (which there may well be), then sirpoc has shown that l literally anyone can drop in into a thread, and if they communicate their ideas clearly, honestly, share their training data and why they have done things, there is a market there for people to listen. You can be a random guy on the internet and write a book. If your ideas work, it will gain momentum. So I have no idea why people are so reluctant to share training they say provides them better progress. The floor is yours.
My view is this: this thread and the wider community has inadvertently been the best case study of all time with regards to hobby jogging. Thousands of runners experimenting with a systematic plan over a long period of time, with a significantly large proportion of them reporting excellent results.
My own view is until someone else does that, I'll probably stick with the general NSM outline and l even less likely to listen to even more random people on the internet who won't even share their own training or outline.
