I think the paddle getting stuck is more a matter of a design fault with some machines.

I've never used vitamin C nor remember seeing it asked for in any recipes that came with the machines. Like you, we prefer a (up to 50/50) mix to a plain wholemeal loaf.

The order of wet/dry ingredients for our Panasonic is different to the order for our previous machines.

The others asked you to add the liquid before adding the dry ingredients. I think the yeast would go on last to avoid contact with the liquid until the mixing started.

This Panasonic tells you to add the dry ingredients before adding the liquid. I guess they feel that gives a better mix but is only possible with (unless you wanted to do it manually) with a machine that times its own adding of the yeast.
