My finding of that the Slow, Normal and Fast relates to the slowest shutter speed choosen for a certain focal length and is offset by a factor of one stop for the different choises.

It is quite possible that focal length figures into the equation as might S/N ratio and raw meter output, though the English appears to be pretty explicit that we are choosing a conservative vs. more dynamic strategy.
I have to confess to not having ever done a controlled test of auto-ISO ramping until tonight and tonight, I am a bit flummoxed. I was not able to get any variation by focal length with the light regime available, but you are essentially correct in regards to how ISO ramps for Slow, Standard, and Fast. There is a one stop difference between the three in regards to ramp start point. I was not able to explore further due to lack of a standard light source.

I was, however, able to reproduce the OP's result with ISO stuck high, paradoxical as it might appear.

I use it for pretty much all work I do and find it to stay as low as possible in any given situation. How the manual is written? Well, let's say that Ricoh must have employed people from Sony to do their manuals. An example would be: For the ?-mode function, press button ?, number 5 in figure 8, to turn on and press again to turn off. But how the function works is anyones guess.

One thing to check would be which program curve is choosen. I use Normal.

The only manuals worse written than camera manuals are software manuals. I think the proverbial infinite number of monkeys would do a better job. We need manual writers who work like this:

Waddaya wanno do? Exposure compensation? Oh: push the button with the add and subtract on it and twiddle the wheel on the back.

The Older manuals were good, they actually helped the buyer understand every aspect of the camera. About all the functions, why not tell us how to use it? Show us the thinking behind the design...
