You can define the sensitivity of what's included with an optional extra variable. A value of 1-100 will change the outcome of what's included. (e.g. iMcVar=2 querying the US right now is showing 37 ISPs, when I change that value to 80 the same query results in 407 ISPs listed, same query without that iMcVar variable results in 506 ISPs listed)
https://testmy.net/?iMcVar=20 (change the value 2 to something between 1-100 -- a higher number includes more)
What I was doing in developing this option was opening two browser tabs/windows. One with the query I wanted to modify and one with the
https://testmy.net/?iMcVar=20 URL. Then modify the iMcVar in one tab and refresh the other until it's displaying the right number of results. Sometimes you might not want to include everything, it doesn't make sense most of the time to look at the ISPs who only have only 1 client testing.
These settings and many more hidden will be included in a new settings control panel. No ETA but it is coming.
