So here's what karl's "ETSOI" transitional steps 3 and 4 look like (steps 1 & 2 being as before):

karl (in effect) said:

3) The (J)>R>S>D loop, getting RSD into place without disturbing the semicolon

 q  w  F {J} G  y  u  i  o  p 
   a {R}{S} T {D} h  N  E  l  ;     The "Tarmak3(ETS)" transitional layout (R>S>D>G>T>F>E>K>N>J)
     z  x  c  v  b  K  m 

4) The (J)>Y>O>;>P loop, getting O in place and finalizing the big loop

 q  w  F {P} G {J} u  i {Y}{;}
   a  R  S  T  D  h  N  E  l {O}    The "Tarmak4(ETSO)" transitional layout (Y>O>;>P>R>S>D>G>T>F>E>K>N>J)
     z  x  c  v  b  K  m 

5) The L>U>I self-contained loop - again, step 5 is simply the full Colemak!

 q  w  F  P  G  J {L}{U} Y  ; 
   a  R  S  T  D  h  N  E {I} O     The Colemak layout (Y>O>;>P>R>S>D>G>T>F>E>K>N>J & L>U>I)
     z  x  c  v  b  K  m
