your policy in this has been quite clear for me. For exampl when in my company is made a new product, it will be tested during several weeks. One extra motivation to test is a competition
like now in NEM.

The product would be tested better, if the testers are using many models. When they would notice that this model is not working, they change and try another.

More diverse testing requires some feedback. Are the testers now getting feedback enough?
