Ok in my current mage impossible game I reached trap medal level 3; no clue how many fights it took

I think I was level 5 or 6 so probably a bit more than some of you. Level 13 now and need 2 more no loss fights to have all medal level iii ('cept orcs, fire arrow, heroes killed and dragons killed).
yea I know I should already have the no-loss medal up to III but I had a lot of 1 death fights I didn't feel like redoing. I suck. Hum. I guess it gets hard now.
Hum. No clue why but it hasn't gotten difficult (at level 24 now). Bit surprise that upping the medals a little made this big of a difference (previous mage on impossible game petered out at level 17; only slight different in medals - mostly 2's where this mage has 3s). Not sure if it is the medals or critters that loaded (this game has a tons of royal griffons AND demon(whatever that can summon demons) in Verona. Last game had crappy critter load - so either medals are everything or more likely the combination of the two.
Of course I'm not trying for no-loss.
