Those colors slide down the RGB scale. Red being the worse and blue being better. Although, sometimes little variance is bad... like sometimes if you encounter a bottleneck along your route. So use your best judgment, don't always go off the color.
e.g. Say you have a 50 Mbps connection but you're scoring only 12 Mbps... BUT the TiP is showing only 5% variance. It's going to show up blue. Obviously you know that something isn't right because you're supposed to have 50 Mbps. What the test saw however is a steady transfer...
You can have a steady clean connection that is limited... just make sure to judge your result in its entirety, the color is only a hint to how steady the connection was... not an indication of if it was a good result or not.
Here's one in red that I wouldn't consider bad... 67% middle variance
... it could have done better, here's a result taken at the same time on a different device. 25% middle variance
Is either one of the above bad? I personally don't think so. But I think it's obvious which performed better. Hint: Just like in a drag race, it's usually the one that accelerated the fastest. As long as there aren't bumps in the road.
Funny story, testing at the same time were a pair of identical LG G2's. One was bogged down with programs running and the other was the better result above.
Here's the result from the bogged down phone.
Now that's a rough ride... something she had running was ruining her connection. Hint: pattern variance (like this example) is usually a major indication to an underlying issue.
She opened the task manager and closed all programs and retested...
... almost mirrored the result of the other phone. Both beat my i5s
Note: In case you didn't know. TiP is measured from 5% to 95% ... the middle of that (or 10% to 90%) is the middle. The variance within that is the middle variance. ... so a large burst or drop off at the beginning or end will not effect the middle variance.
I hope this answers your questions and then some about TiP. It's something I made up and never really explained. I guess I'm always aiming to build something that doesn't need explaining. ... I'll keep working at it.
