That's why grinding floors around T500 with Adv seems impossible, even F2Ps can bypass it with Ex difficulity. Another thing is RNGesus both on rune boss and material drops. Ever got no rune time for a day, also desperately need Serpent Slayers to drop. Personally I'm grinding on time (except on bed time when I sometime ignore my alarm).
