A team's NET and quality of resume are not nearly as linear as you are implying above. I suspect you were doing it in that way to try to simplify the analysis, but I think it may have over-simplified things too much.
We agree on the following:
1) The game helped our NIT chances more than our NCAA chances (Obviously)
2) From your prior post I think we both agree that this team going 5-1 to close the regular season is a herculean and unlikely task. (I'll get back to the 5-1 below)
The problem I have with your analysis is that you appear to be making a linear correlation between a team's NET and the quality of its NCAA resume or NIT resume. And that is clearly not the way it the NCAA or NIT committee does things (except for 12 NIT spots)
a) While our NET is #85, or tournament resume is much stronger than #85. We know that margin has killed our NET - but those are not the things that the committee looks at -- Q1/Q2 wins, Q1/Q2 win%, # of bad losses are the things they focus on, not individual NET. Just go to the Warren Nolan Nitty Gritty - you can fairly easily find a dozen teams with NET's above us that have weaker resumes. And its hard to find any teams with a NET below #85 that has a resume better than us.
That is not to say we have a NCAA tournament worthy resume right now either. We don't and we have serious work to do.
b) We have seen P6 teams with a NET of #40 miss. And those with a NET of #77 get in (thanks to Wiseman for finding those details earlier). Last year we had Pitt with a NET of #67 get in. In the BIG last year #40 Rutgers and #80 Wisconsin were treated basically the same by the committee. Once you get between #40-#70 your NET doesn't have that strong a correlation to the quality of your resume.
So where am I heading ...
Regarding the NCAA - I think we both agree that 5-1 will be very difficult to close. But I am fairly certain we disagree on where we are if we close 5-1. To me if we close at 5-1, we will likely be very much around the line (probably just below it). Really wish we didn't have that Q3 loss to FSU so that our resume could be clean out of Q1/Q2 right now. But our Q1/Q2/bad loss metrics will certainly be satisfactory if we go 5-1. Will it be enough entering ACC week, probably not, but it will not be far off. Of course as I say when ever these things are discussed, we will likely never find out who is right or wrong.
Regarding the NIT - I'm going to make a separate post on this, but we are a near lock for the NIT. Yes there are 12 of the 32 auto bids, that we will likely not get. But there are 20 selections, and they no longer grant auto spots to regular season champs. As of now, we easily get one of those 20 spots. The NIT is going to be the P6 invitational this year under the new format.
