Yep, and adding 6x the amount of crystal 20 won't get you the same flavor as crystal 120 simply because that longer kilning produces deeper, darker flavors.
keep that in mind when doing crystal substitutes for color...sub 80 for 120 (i.e. as close as you can get, and run a calculator for the proportion to use to get teh same SRM)
