Well, as a patron, I don't mind at all that the creators I currently support both don't release monthly, since I know that everytime they do, I'm in for a treat anyway. In fact, I haven't got one single game in my "great games" list that do release monthly*, and I wouldn't want the devs I respect to burn themselves to reach an arbitrary release date only to shit out something they wouldn't be proud of.
If you look at it with a bit of hindsight, once the game is done, what would you rather have? A streak of chapters/episodes/events poorly articulated with rushed out renders or a full well adjusted game with a coherent storyflow? All the devs here are mainly letting us play the alpha version of their game, and when you pledge on patron, you're not exactly buying the product, you're just using your money to say to a creator: "I like what you do, please keep going".
That being said, now that I'm a developer (sort of), I already feel kinda guilty for not releasing faster D:
Then, you have the case of devs who go mute for months, and maybe post a render or two once. Even if their game is great, the lack of communication makes it more difficult to support them.
Certainly it's an issue I'm wrestling with myself as, by my reckoning, I can release a chapter every six weeks. Anything less than that would be a part chapter only.
I'd like to comment on that, if you'll let me. You say you can release a chapter every six weeks, BUT how long did you spend crafting everything, every little details, every characters personality and looks, before the first chapter even got released? The monthly support alone wouldn't reflect that. Which brings me to my point, after all this rambling.
So to answer your question,
Wol, my support does depend on the dev themselves. If the dev is a great chap, I support, if the dev creates the best game in the world but I have no affinity with them as a person, I don't. Ultimately, the release cycle does not really come into consideration.

edit. I'm lying, Belle (Long Live the Princess) usually does release monthly, but that's more like the exception to the rule.
