People at HN are typically analytical thinkers who appreciate fact over conjecture. Your post starts with “I have a feeling.”

And any analytical mind can take some educated guesses and say 'well, if I pour 6L of a poison in an average public swimming pool of 30x2x10m, that's 1 part poison per 100.000 parts water, or 0,00001% poison. Same goes for the atmosphere and blasted up particles. Aside from that, most people would read'I feel like' ~= 'I guesstimate', but it seems these days some of us need explicitness past the normal verbal conventions.
