The "secret" was the K5(touch). The other models were just added to the thread to expand its scope (which is why they are confined primarily to the first paragraph, highlighted in dark red to indicate that they are an add-on).
Most of my posts are to benefit people who do not already know this. Insiders such as yourself who already know the information I post do not need to get "bent out of shape" over who "discovered" what before I did. I do not need to go down in history as a great discoverer, just a simple "Thank You" is enough.
Those who are upset because I posted too many messages or because they knew something before I published it, or because I used "big" words like "research", "discover", "invent", and other leadership words, and those who direct hostility at me out of jealous rage, are welcome to join others on my newly-activated "Ignore" list if they get too annoying for me to bear.
I hope you treat others with respect and kindness, as I try to do.
