I believe it would be handy, but it depends on the size. Right now I think it's reasonably fast and intuitive for models of around 3 to 40 metrics(variables). If you have more it could get slower, especially if many of them have to be recalculated at once.

I suggest trying it out. If nothing else, you may be able to begin with very simple models of the most important variables.

It was around 6-8 metrics so i guess it would be fine?

Definitely. Here's one in that range as an example. http://getguesstimate.com/models/163

Feel free to play with it. You can edit it, just not save it. (I recently realized this was not obvious to most people)
