Specto scores explained: accuracy, power and the trend

A Specto report is full of numbers. Which ones matter, and how do you see whether your training works? This article explains the two scores BowlUp Tracker calculates for you and shows how to follow them over several sessions.

Accuracy score: how consistent are you?

The accuracy score is the sum of the spread at four places: at the laydown, at the arrows, at the breakpoint and at the entry. Spread is how far apart your shots land at that place. Lower is better: a small spread means your ball follows almost the same path every time.

A low score therefore says something about repeatability, not about where you throw. You can be consistently off your line and still have a good score. That is useful: first consistent, then aim.

Power score: speed and rev rate together

The power score is the speed in mph times the rev rate (rpm), divided by 1000. Higher means more power behind the ball. It helps you see whether speed and rotation are in balance.

Why BowlUp recalculates them

BowlUp only reads the individual values from the report and recalculates both scores itself, so the numbers always match the shots. The PDF stays in your own browser; nothing of the file is stored.

The trend: do not judge one session

One session says little: a bad day or a different lane can shift everything. The value is in the trend over several sessions. Pick a value in the student file (accuracy, power, speed or impact angle) and see how it develops. If the accuracy score goes down, the spread is getting smaller: you are becoming more consistent.

Rpm is deliberately left out of the trend line. It is a calculated value that is easy to influence, so it is not a good yardstick for progress.

Sharing with your student

As the coach you decide per session whether the student sees it. A shared session appears in the student portal under Measurements, in plain language: two score cards, three numbers with a trend arrow and your comment.
