/ Acclimatisation profiles for standard treks at altitude

Is there a medically approved "safe"acclimatisation profile published anywhere? Something which trekking companies adhere to for standard popular climbs / treks at altitude such as Everest Base Camp, Kili, Kinabalu etc.? I am after some evidence to support a 3 night ascent profile of 0m - 2700m - 3300m as being within what would generally be seen as acceptable in terms of safe ascent rates.
Thanks in advance!

Superb, just the ticket, thanks.

In reply to JohnV:
The Wilderness Medicine Society recommends that once above 3000m, you should stick to a maximum ascent of 500m per day, with a rest day (no ascent) every 3-4 days or 1000m.
You can climb higher each day (including the rest day) but should sleep no higher than this.
This is "safe" for most people - some people will still get AMS, especially if other factors are involved (stomach bugs, colds, strenuous activity, etc.)

What trekking companies actually do is not necessarily in line with this, for example a 5-day ascent of the Coca-Cola route on Kilimanjaro is much faster (and causes very high rates of serious altitude-related illness).

0m - 2700m - 3300m would probably be an acceptable ascent profile. Altitude can be unpredictable and still cause problems on "safe" ascent profiles, so a bit of common sense is still necessary.
