Do you find the brake settings make a big difference?
Yes... always set it to 'standard'... 'low' just means you'll be burning off potential electrons as heat while you slow down. This will have an even greater effect if there's a really big hill involved where 'low' can't keep you going slow enough. In theory on flat ground 'low' could be just as good as 'standard', but only if you can manage to never touch the brakes at all without crashing into anyone.
