Fixed effects model: changing the F, p values [Two-Stage / GS Designs]
for the results consistency (R versus Phoenix as you reported), there should be one more term of marvelous effect x) ... you posted it as number 7: (I resorted it for comparison of F and p values, note: int and Trt are missing in the results from R code)

If you change the muddle:
muddle <- lm(log(Var)~Group+Seq+Seq*Group+Subj%in%(Seq)+Per%in%Group+Trt+Group*Trt, data=data)
and run the mentioned code... Voilà!
Type III sum of squares:
(mimicing SAS/SPSS but with Seq tested against Subj)
log(Var) ~ Group + Seq + Seq * Group + Subj %in% (Seq * Group) + ...

The comparison is telling us that with groups it will be little bit more complicated.
❝ Now Group factor seems to be more suitable.
❝ What bothers me is that Group effect is not equal in R and PHX, cannot figure out the reason
