I had decades of experience in 68k assembler coding and wrote all kinds of hardware scrolling routines since the 80s, but it lasted until 2012, when I read Georg Steger‘s ScrollingTrick (Aminet), before I understood how to do a decent „corkscrew“ scroller.
I felt really dumb, because I thought about scrolling techniques so many times, but I was never able to develop this idea myself.
