1. Re load
- Does the indicator of 1.00 == no extra load?
no.? ?0 = no extra load.? Remember it is exponential, so on a five point scale, 1 is only a bit more 2 as a fair bit more ... 5 is a hell of a lot.
- Load indicator seems to positive and negative but I can't determine why or whether this matters
- I can't figure out the load algorithm (3 load steps, load multiplier 100) load goes from 1.00 to 1.30 to 2.20 to 3.70
That is not a load indicator.? That is, behind-the-scenes, a momentum calculation.? It is combination of the load and brake. I intend to hide it in the final versions.
- When I set the load multiplier to 20 or 200, I get the same progression. A bug? Or am I doing something wrong?
umm... I see a huge difference in the momentum calculation.
Setting up these parameters for reasonable loco performance is requires a fair bit of "try it and see" given that I am also working with decoder momentum, so understanding the relationship of load step to throttle impact would be really helpful. I am assuming that that is what the load indicator is intended to provide.
Ok, I'll document it.

2. Re brakes
- I have been using the ESU three brake option - functions 4, 5, and 6.
- To keep it simple I have 3 brake steps
- Brake steps 1, 2 and 3 activate F4, F5 and F6 as expected. I like how it highlights the function in the normal function button section of the throttle.
- What is the slider bar to the immediate left of the brake panel showing?
That is an attempt to represent the air reservoir. If the reservoir is empty You can't apply brake, or full brake.
i.e. if you dump the brakes, the reservoir empties.? You can't fully reapply till it fills.

3. Re Accel/Decel settings
- The Repeat Delay setting implies it goes up from 1 msec. But it seems like there is some slower minimum speed step repeat delay. about 1 sec? True?
I don't see that. For me it steps at about the rate set. It won't be exactly that as it sends then receives a response, so there can be a little bit of delay.
?
The combination of the repeat delay(s) and the step effectively set the base momentum (no load) on the loco.
