Is puzzle storm adjusted to your rating?

The puzzles seem easier or increase in difficulty more slowly the lower my tactics rating but that might be confirmation bias.

No, Puzzle Storm and Puzzle Streak always start at the same puzzle difficulty and increase the same with each puzzle.

Unfortunately I cannot confirm @benwerner 's answer. According to what I observe in the case of puzzle storm the rating of the first puzzle is sometimes ca. 900, sometimes ca. 1000 and sometimes ca. 1050 in a completely aleatoric manner.

@jsch61KA That's because a random puzzle of a specific range is chosen. @benwerner is right, just that the start difficulty he mentioned is defined by a specific range, not one exact number
