The last Defense Authorizations bill actually allowed VSP for 6-20 years and VSP up to 4x Involuntary Separation Pay (ISP), but the SECAF limited it to 6 years to "no more than exactly" 12 years and VSP = 2x ISP for FY07.
It seems to me that the next VSP group would be more like 13-15 years, since they'd end up double-tapping the 1995 yeargroup. The last matrix (12 July) showed 570 overages total for the 1992-1994 yeargroups.
Question for wickedsprint - for The FY07 VSP amount was 2x Involuntary Sep. Pay, any words on what the FY08 VSP amount might be? Is 4x a possibility. I'd think it would have to be more than 2x for enough Majors & LtCols to take the VSP option.
