Yeah, it's a good point, and I'm indeed a bit guilty of hoarding data I can't immediately process. However, the problem with the 'objective first' approach is that it's gonna require a lot of data to draw meaningful rigorous conclusions from small interventions, so I'm making sure to 'secure' the data first, and then gradually process it. But also, it's a challenge in itself -- I'm automating a lot, sharing my system and trying to interoperate with existing tools, in the hope that my work can be useful to other people and make quantified self easier for them.
