Interesting article!
My perception is that staking frequency is primarily influenced by network weight. That might means that some of the forking over the past month could affect that.
I also think that staking every 6 months is the minimum, but it is definitely very reassuring to stake more frequently! Plus you get a little more compound interest by staking more frequently.
Thanks for your post,
