@pcola,
WeMeantWell pretty much hit the nail on the cranium - I only have a couple of things to add. Don't try to "alibi" the Q3, just focus on your strengths, and have your recommendation writers focus on your strengths. The fact that you don't have a MWS IP qual is completely mitigated by the fact that you were a C-21 IP. The biggest reason that TPS AFMC wants prior IPs is so your future AFMC Squadron isn't required by AFI to send you to a formal IP school for your future IP ugrade, they can do it in-house. This saves TDY time and $$, time being the most important factor.
As to the FWIC -> TPS route, I'd say that those are 6 sigma (yes I'm a geek) outliers and some special circumstances. Honestly, you aren't doing anyone any favors if you plan to go and use up years and millions of the AF's $$ going to FWIC and then back to the CAF, then turn around and go to TPS. There is a reason that most of the OT guys are FWIC graduates - that's where they are needed. DT is an entirely different mindset. Not that FWIC guys can't do it, most of those guys can do anything, it's just that it is a waste of their f*#(ing time.
Cheers,
Jason
