I recommend a slightly lower temperature for the filter, around 91°C is fine. And just bloom + pour once, or twice if you want it stronger, but it's good to remember that decaf always has more fine particles than normal coffee, so the filter can easily clog up. Personally, I like Cafec filters for decaf, the green ones (competition cup), because they clog the least and flow the fastest. It's a bit too dark for the filter, but it definitely works and is good enough. Surprisingly, it tastes quite coffee-like for this production method. Good in my opinion.
