Hi Dave, you are right, the ramping feature ramps the intervals.
So let's say you start a timelapse during the day with 10 secs interval. You'll be using an external ramping tool (like qDslrDashboard) to control the camera, and eventually when it gets dark, your exposure times will be at 8 secs and could not be increased anymore because of your interval of 10 secs. Now you could use the interval-ramping to increase the intervals gradually. Of course this would lead to an acceleration in the final clip.
Okay - now how to set this up.
First click "right" and choose Ramp Interval in the LRTPTF.
Now choose the time, that it should take to go to your destination interval, for example 20 minutes. This means from now on in 20 minutes ther LRTPTF will have reached the final interval that you will define next.
Click right and now you can define this final interval, for example 20 secs. After you click right again, the LRTPTF will start ramping the interval. It will take 20 minutes to get from 8secs interval to 20 secs. While ramping, you'll get a "*" indicator on the display and you can observe that your intervals on the top right of the display will get longer and the remaining time (bottom left) will get longer too of course.
That's it! Reaching a longer interval means that you could further push your exposure times, for example by changing the "Longest Exposure time" in qDslrDashboard to 18 secs after you reached your 20 secs interval.
Regarding the 99,9 secs interval limit: Yes, and for normal timelapse it's more than enough. However, there might be long-term applications (for timelapses over months and years) where longer intervals may be desired. I've now pushed a new version (0.90) to GitHub, where the limit for intervals is 999 secs.
