Is momentum real in tennis?
It is debated. Players and fans feel it strongly, but statistically it is hard to prove. This index turns recent games, breaks and holds into a transparent score, clearly labelled illustrative.

Frequently asked questions
Why are breaks of serve weighted highest?
Because breaking an opponent's serve is the hardest and most decisive event in a set. The index reflects that, though the exact weighting is a teaching choice.
What does the score tell me?
A rough read on who has the upper hand right now, based on the recent run of games. It is a snapshot of the swing, not a prediction of the result.
Can momentum shift suddenly?
Yes, which is part of why it is so hard to measure. A single break or a let cord can flip a match, so any momentum reading is fragile.
Should I bet on this?
No. It is a teaching tool to explore the idea of momentum, not a forecasting model.
