That's true, but due to distribution the numbers are far less than they could have been.

But that's something that I think some manufacturers are starting to forget about: custom installers need the work done by prosumers. Prosumers have a lot more time to devote to troubleshooting, finding workaround, pushing the limits, uploading configurations, developing new layouts, and are generally open to sharing for free something they may have spent hundreds of hours working on.

If your keep your prosumers happy, your custom installers will be even happier.
