Building a bag that has no holes
Matched because two of your clubs cover the same six yards, which leaves seventeen yards under them with nothing to hit.
Trackman iO + Trackman iO vs Trackman iO + AVA
An indoor bay is the cleanest read you will get on strike and delivery. Below: what one iO session shows you, what a winter of them is worth, and what AVA does with the numbers indoors is honest about.

One block, two readouts
Seventy-one 7-irons. One of them told you something.
Both columns describe the same forty minutes in the bay. The left one is accurate and complete. The right one is the one you can act on.

The finding
You practised the club you already own. Your 7 and 8-iron carry within six yards of each other, which leaves seventeen yards under them with nothing to hit — and that band is where eight of your last twelve approach shots came from.
Three setups, side by side
What each setup can actually tell you
The iO is built for a ceiling: club delivery and strike are its strongest ground, and carry indoors is modelled from launch rather than watched to the end.

Use the bay for what the bay changes — strike, delivery, start line — and let the course set your yardages. AVA holds both sides and reports the difference between them as its own finding.

Then someone shows you how to fix it
Finding the leak is half of it. AVA matches what your sessions exposed to lessons from nationally ranked teaching professionals, and rebuilds the playlist as your game moves. No lesson fees, no drill library to search.

Centre strike before ball speed
Your short misses are strike, not swing. This is the block that finds the middle of the face before it chases another yard.

Start line, then shape
The whole session misses the same direction with every club, which is a setup fix rather than a swing rebuild.

A session with a scorecard
Blocked reps stop paying after sixty balls. This is the structure that keeps the last forty worth hitting.
Matched, not browsed
The playlist follows the data
Lessons are selected against the leak your own data exposed. You do not search a library and guess which video applies to you.

When the most expensive thing in your game stops being the most expensive thing, the playlist changes to whatever is.

TRACKMAN IO + AVA GOLF
Turn your Trackman iO sessions into lower scores
What a bay is genuinely best at
Strike and delivery. Nothing varies: same lie, same ball, same light, no wind to read and no slope to stand on. Every source of noise that muddies an outdoor comparison is held still.
That makes an indoor session the right place to answer 'is my strike improving?' and 'is my miss a face pattern or a path pattern?': questions that need repeatability more than they need distance.
It is also the right place to find strike decay. In a bay the balls are unlimited, which is exactly why the sixty-ball cliff in the sample session matters more indoors than out.
The one number to hold loosely
Carry. Radar infers less the more flight it sees, and a bay gives it a few feet. Trackman's indoor engineering is very good and it is still solving a harder problem than the same unit outdoors.
So AVA does something specific with it: an indoor carry sets an upper bound and a relative comparison (this club versus that club, this month versus last) while the yardages you actually play to come from outdoor sessions and tracked rounds.
That distinction is not pedantry. A gapping ladder built on indoor numbers and played on a course is how a golfer ends up eight feet short of every pin all summer.
A winter indoors, checked in April
The real test of a bay winter is not the numbers in March. It is the scorecard in April, and that is a comparison almost nobody sets up in advance.
AVA holds sessions and rounds on one timeline for exactly this. If strike quality is genuinely up and scoring has not moved, the finding is not in your full swing: it is in decisions, short game, or a bag that does not cover its distances.
That is a far more useful conclusion than another winter of delivery work, and it is only available if the indoor and outdoor data live in the same place.
Trackman iO questions, answered
Is indoor Trackman data worse than outdoor?
Not worse, different. Strike and delivery are arguably better indoors because nothing varies. Carry is more heavily modelled because the unit sees less flight, so AVA treats indoor carry as a ceiling and sources yardages from outdoor and on-course data.
Can I compare iO sessions to outdoor Trackman 4 sessions?
Yes. Shared parameters line up, and AVA keeps them as separate contexts rather than averaging them, which is what stops an indoor carry quietly overwriting a course yardage.
Should I tag clubs during the session?
It is worth the thirty seconds. Club-tagged blocks let AVA score dispersion per club instead of as one blended pattern, which makes the findings a lot more specific.
How long should a bay session be?
Shorter than you think. In the sample session smash factor falls off after sixty balls: everything past that rehearses a swing you don't own. AVA finds your own break point rather than assuming a number.
Does AVA change anything in my Trackman account?
No. AVA reads the file you export and never writes back.
