#TODO: 3 (N?) different sizes for every position and it would rotate through them
# +-20,25 or 30% change --> 3 stages are enough
# 1. it needs to detect whether it is already at the position 
# 2. it needs to detect what is the next size based on the current size
# 3. change the size to the next one
