Rain interval went from 0.4s +- 0.25 to 0.2s +- 0.12, which measures 28 drops in 6 seconds instead of 13 and keeps about 24 bullets in the air at once. Three walkers are placed back in level 3, on the corridor at cells (10,11) and (17,11) and on the left ledge at (5,10); they only patrol and hurt on contact, since their firing was removed earlier.
