It seems a reasonable schedule ;)
I am not that talented or skilled lol
But I have been in multiple community of text based games where authors usually does this
Also a discord server helps keeps the community togather
And yes if u do see urself doing this long time, I would advise opening a Patreon also take 4 weeks if u need for the first 30k update then u can do it 15k per 2 weeks or a bit less depending on ur time ofc
