Ah, I see! Thanks, this makes it clear and also renders my question 1 irrelevant, indeed.
In my opinion it would make sense to add the clarification to the manual, e.g. to
http://manual.zorro-trader.com/ddscale.htm
http://manual.zorro-trader.com/zsystems.htm
The pages currently state "run a backtest with the Capital slider at the same position as in live trading at session start" and "Before starting live, run a backtest with the Capital slider at the same position as in the trading session".
So, if the reader knows that "stop and resume" means a new "trading session", then it is clear implicitly. But explicitly explaining the need of a new backtest with the current slider position after stop and resume would make that more unambiguous.
