Thank you. See my reply to the prior question below.
As to prioritization of contributions, I think the order is to first apply unused carryover from prior years, then cash contributions, then appreciated assets like stock. So my approach was to use the full 30% permitted for appreciated stock to get max tax savings and then limit cash contributions to 20% so the total would not go over the assumed max of 50% under the most conservative assumptions.
As noted, this a first time / one time issue for me so I decided to cap it at the safer 50%. Its beyond my ability to make any further sense of it. Thanks.
