In our lab, we prefer longer stages in the aerobically fit, so that we get a better handle on your HR. I use a minimum of 4 min stages in the ultra athlete, for the very reasons you describe.

In terms of your lactate testing, I agree with Scott – I suspect the drink +/- dydration would explain it. One other quick thought – we did have a batch of out of date test strips that gave some anomalous readings a while back – maybe just check the expiry dates. Likely not that but an easy check.
