In the Elapsed include:

T1PS = 1                             ; start with 1:1 postscaler
TimerConst = ((OSC*1000000)/4/100)   ; how many timer ticks will it take
  while TimerConst > 65400           ; if it's more than the timer can count
T1PS = T1PS * 2                      ;   double the postscaler
TimerConst = TimerConst / 2          ;   halve the count
  endw
TimerConst = 65536 - TimerConst + 8  ; final reload value

Darryl talks about a post-scaler. Timers 1, 3 and 5 have none for a 18F44K22?

Neither does Timer 0, only Timers 2,4 and 6 have pre and post-scalers.
