Mevo+ issues

[deason]

Hi,

Im finding I get some funny yardages for my swing/club speed.

Admitted spin is high but does this look right to you?

These are 1 piece shtty range balls and its winter in the UK.

That vertical launch angle is really low... I bet your peak height isn't very high either... try to get your launch up to around 11 degrees... getting your AoA into positive numbers may help increase your launch... swing up.

That jumps out at me as well. A 6 degree vertical launch (corresponds with AoA of -2) is really low. Factor in a crappy range ball and the carry is likely not far off. Swing speed and ball speed are really good though. Impressive. Launch it higher with a lower spinning ball and your carry distance will increase greatly.

Thanks guys, you are confirming what I think is the doozy in this whole set of number (Launch angle).

Wondering if im sliding forwards and sweeping driver too much. This is a stupid rubber tee in the mat used that's 1.5 inches so I'll test higher tees.

With launch monitors, the quality of the ball itself is everything. Garbage in, garbage out.

AOA, for one, is setup dependent so if the height of your mat is not set correctly in the Mevo, this could be a factor.

AOA, for one, is setup dependent so if the height of your mat is not set correctly in the Mevo, this could be a factor.

Any idea how sensitive it is for AoA? For instance if the area between the ball and the unit is not dead level than there is an elevation difference that is not being accounted for. In my garage I know my floor slopes at 2% so with 7' of distance between ball and unit that is an additional 1.6" (4 cm) that I put into the app in addition to the mat height. At the range this likely gets left out. All this data available but without a meticulous set up the numbers can be affected. Wondering about this for the new data coming as well. Like putting the ball directly on the target line to get accurate path measurements, putting the ball exactly at the distance input from the unit, etc . . .

[pcascio]

Not sure, but AOA is dealing with the smallest range of motion, so I'd imagine it's pretty sensitive to not only the mat height setting, but also the distance to the tee. Both would effect the calculation of AOA.

Does irk me that getting setup is so important with mevo+, you'd be led to believe the thing is easy enough to setup but it really isn't I am finding.

Surely the device can tell how far out you are at different heights as its adjusting something on the mevo device???

Got some better figures working my AoA a bit better. This was also 2 piece proper ball.

The X3 does all that automatically (even self-levels) but it's also about 5x more expensive. *shrug*

Not a swing coach or anything but you may want to work on your path getting more from the inside.

A couple things stuck out while reading your numbers. You're launching the ball left of the target line with left spin axis which tells me your closing the face well but striking it in the toe and this shows up again with your smash factor being low. You have a ton of club speed but losing so much energy from the off center strike. If you work on coming from the inside you can move the ball forward in your stand and help more with AoA. If you move it forward now the strike will just get worse without the club path change.

preludesam - With the data given how can you determine that the strike location was on the toe? The spin axis with the left spin could indicate the strike off the toe but the starting H launch is still slightly left. I would think the toe strike would open the face and move the starting H launch direction further right (?). Said another way, he should be hitting pull and pull fades on well struck shots because of the assumed out to in swing path. What is your typical ball flight deason? Are you in fact hitting it off the toe?

This is where the path and FTP data would help clarify what is going on. Relatedly, I would like to understand the impact on the Face Angle numbers (FTP, FTT) from off center strikes. Flightscope has told me that the face angle in the Pro Package is not measured directly but calculated from measured path and H launch data. If true then toe strikes will show a FTP number that is more open then the actual delivered face angle due to gear effect. How much is not clear to me. I'm assuming I will be able to tell when gear effect is impacting things, even moderately. Don't want to work on closing the face more when it is really just impact location that needs work . . .

[preludesam]

I just looked at the data and have been getting into ball flight physics for the last couple years. Reading a ton of data on amateurs and pros and watching tons of lessons online and in person. In addition to what I mentioned before the toe strike shows up in the smash factor but height is the second tell. Low smash and low height is a closed club face and it seemed more reasonable for a toe strike with the spin axis. With that much club speed we should be seeing a higher ball speed hence the off center strike. Normally to optimize distance on the driver you want to see the club speed match the height, within reason obviously. Also that’s quite a bit of left spin axis and with face angle being about seventy percentage of launch direction it’s likely the path is left along with the face.

I could be wrong but I like the mystery game of reading the numbers and I keeps me sharp for future instances. It would be nice to know if I’m right though…
