Thanks @dj123. This is a good approach to overcoming the SP delegation "pause" if indeed it is the way un-delegating works.

Even if we didn't fiddle with the numbers, I think the delegation "pause" isn't a major concern. The reason is that my first intention with this service is to get mostly minnows donating SP delegation to @delegateforaday. And as us minnows know, it doesn't really make much difference if we have SP at the low levels we possess it at. Over a week, my 110SP earns me about 10 cents of curation rewards or thereabouts. Minnows aren't going to miss their SP for a week.

Of course, I was also hoping to get some larger players and whales on board too, and I'd still like that to continue even if there is a "delegation pause". Hopefully they will see the benefit of such a minnow support project that they will be ok to forgo a week's earnings on some of their SP. If this is too big an ask from them, I would consider running the Delegate For A Day project less frequently so as to make the "loss" for them less of a concern.
