Does the AutoSet T allow you to adjust the algorithms in a similar manner to the AutoAdjust?

No, it doesn't. Which is one of the few negatives about the AutoSet T. On the other hand, the main thing the AutoAdjust LT hypopnea parameters do is to force the AutoAdjust LT to raise pressure faster than it does for the default hypopnea defintion. The AutoSet T raises pressure fast enough (but not too fast), that this is probably not an issue in most cases.

Does the AutoSet T record the
same data as the AutoAdjust ie. exhale puffs etc.?

The AutoSet T GRAPHS pressure, leaks, and apneas, while the AutoAdjust LT graphs only pressure. The AutoAdjust LT COUNTS apneas, hypopneas, leak minutes, "mixed events", and exhale puffs. You can infer the number of hypopneas with the AutoSet by subtracting the apneas/hour from the AHI and dividing by the number of hours. Overall, the AutoSet T provides superior information.

You seem to respond well to treatment with both the AutoSet T and the AutoAdjust. Have you ever used a conventional
CPAP? If so, how did you do on it? Could you perhaps include conventional CPAP on your comparison site as well as the 2
APAPs?

I've used both the Horizon LT (which may be the worst conventional CPAP on the market), and the Sullivan V Elite (which may be the best). The Horizon LT is like a jet engine and has the same horrible pressure response as the AutoAdjust LT, while the Elite is quiet and fast. Not much else to say about those two. MHAM
