Regarding relevant in a form

I'm currently task with creating a form for road maintenance and may
include a lot of relevant. The ODK currently used is ODK v1.4.
Just curious how many relevant can a node handle? One of my senior told me
that there is a limit, and crossing that limit will crash ODK.
Thanks in advance

First, you should upgrade to the latest software. https://opendatakit.org/

The device you are using will limit the complexity of your form.

Tablets with higher resolution screens will have more memory, which will
allow more complex forms to be processed.

As you move to cheaper, lower-resolution, phones, the complexity of your
forms will need to decline because they will have less available memory.

At some point, the time it takes to load or advance through the form will
become too slow to be usable.

There are many surveys being collected with 100's or 1000's of questions.

Sorry for late reply, first sorry if my question is vague.
what I mean for relevant is this

<bind nodeset="/data/mystring" type="string"
relevant="selected(/widgets/branch, 'n')"/>

how many condition in relevant that I can put before it crashes. And for
updating the ODK will take some time as the ODK we currently using has been
modified and will require some time to port all the changes should we
upgrade.
Thanks

And my reply has to be similarly vague.

You really need to test the form on whatever device you are using.

The very latest ODK Collect has enhancements that improve the speed and
reduce the memory used when evaluating constraints.

Very large forms, with very complex constraints are being used. How large
depends upon the capabilities of the device.
