text: Table 11: Average upgrade rates for gadgets generated without (“Orig.”) and with (“PPL-opt.”) low-perplexity optimiza- 
  tion, for the balancing coefficient α = 0.01. In some cases, optimizing for low perplexity has a negative effect on the 
  attack success rate, however the attack can still be considered successful. A more careful choice of α can potentially limit 
  the effect on the attack success.
