Roadies have been known to post the occasional stupid question too.
I find that being on my trainer yields about 5% less in my power numbers for a given HR, so taking your indoor numbers to training outside might be a little off. It's probably close enough to get you started though. The first time testing may not yield the best results either, but as you test more, you'll get better at it.
