Hi @doctormstein1
I had posted an explanation before, comment link- https://discussions.tomtom.com/en/discussion/comment/1648667/#Comment_1648667
The firmware learns your driving behaviour and accordingly gives you an option to take an alternative route which you may have taken before. If that route is faster it shows that green blob and if its slower then it displays the purple blob.
It's just an enhancement feature.
