For those who have hit a putt and it breaks no where near what the dots are showing, here is a strategy to adjust for those "lying dots".
Intro
There are no such thing as "lying dots". It all has to do with the angle of the putting grid and how it relates to your ball and the hole (sort of like how the wind angle shown isn't exactly correct if your avatar isn't perfectly aligned with the pin on an approach shot). I'll attempt to explain it with the examples below.
Examples
1) Lets say you have a uphill putt.
If you line the putting grid up with your ball and the hole, it forms a perfect line. This means whatever direction the dots are moving that's exactly how the putt will break . Ideally every putt should look like this, but WGT is made by a compilation of pictures so not everything lines up perfectly (see examples below).
2) Now let's say you have the uphill putt below:
See how the putting grid is rotated in relation to the ball and the hole. The dots show a right to left break from the viewpoint of the avatar but it is actually a straight uphill putt with no break. Because the putting grid is rotated, it doesn't form a perfect line with the ball and the hole. Right to left movement of the dots is due to the upslope and rotation of the putting grid (This causes the dots to move "down" the slope from right to left).
3) This example shows the opposite situation to example 2:
Again the putting grid is not aligned with the ball and the hole. The dots will show that there is a severe left to right break from the viewpoint of the avatar. However, the left to right break is actually very minor (almost a straight uphill putt). Left to right movement of the dots is due to rotation of the putting grid causing the dots to move down the slope from left to right.
4) For downhill putts its the same effect if the putting grid isn't perfectly lined up:
This putt will show slightly more of a right to left break than there really is.
5) For flat putts the dots are accurate enough that if the putting grid is rotated it doesn't affect the break on the putt very much.
Strategy
I can usually figure out how much the dots are "lying" by using front and reverse camera angles and comparing how rotated the putting grid is (but takes a bit of practice). The different camera angles may show different breaks but once you correct for it with this method you will end up with one break that you can be confident in.
