You asked what we think. Here's my thinking on your questions:
You are going through recruitment as a sophomore. There are numerous threads on GC that address that topic. You likely know the status of sophomore PNMs at your school. That's the bottom line. You've already answered your own question, in all honesty.
Each chapter will maintain its own records re:recruitment and that is not something that anyone can give you information about in the global sense that you're seeking. Can't comment on how chapters (other than my own) view re-rushers or whether or not you'd be remembered. For some chapters, no big deal; for others, kiss of death. Sorry.
Advice: what FSUZeta said in her second paragraph. Your recruitment outcome will be your own individually, and you do have some influence over the factors she listed.
(And I think you meant "acclimated" instead of "accumulated"
)
