Maybe Grin could benefit from recent DAA research?!
Jonathan also made a great accompanying video explaining the tool in detail:

Here’s a comparison of Grin’s current DAA with some increased dampening variants as well as 4 versions of the simpler wtema:

Nice, I was waiting for a benchmark graph. No screenshot?
I am lazy to install and run, cannot do it from my mobile phone.
So since Grin is expected to have ASICs, this is to prepare for a scenario when there will be coins using the same PoW algorithm and hence we want to give them less incentive to switch networks by reducing the difficulty fluctuation?
I think it will be useful even before asics, as general-purpose GPUs can mine and switch between different chains, grin being one of them.

This is simply to improve the DAA regardless of whether ASICs appear. While this tool was developed for studying BCH hashrate variations caused by miners switching to/from Bitcoin, Grin has similar variations due to miners switching to/from all other GPU mined coins.
In the latest version I made the wtema half-lives a multiple of 60,
which fits Grin better. The former multiples of 144 were due to BCH using a 144 block window which is expected to take 144 * 10 mins = 1 day.
You can also see how Grin’s 60 block window with damping factor 3 has similar response time to a 180 block window with no damping.
