A very educated guess. Research studies have correlated this type of test to lab accuracy. Actual threshold's (as measured in a lab setting) may be 2-3bpm's higher, but that's about it. In the end, though, yes: it's only as accurate as you make it. If you really don't "give it your all", then the results could be off. But, if you don't give it your all in this type a setting, maybe you really don't have any more to give?
