                usage logs, gin, reefer.   I drink more brandy, or vermouth or other bottles, with water, than gin, but I have been logging only the gin bottles usage so far, since mid 2014.   For reefer, I began logging my usage mid 2020.   Various previous usage; looking to get back to 50 or 100 mg ganja per day, 150 maybe.   Files last updated, February, March, 2021.   Thinking about logging the consumption of all of my bottles or cases of cans of alcohol spirit or beverage.   I use about a teaspoon per day of instant coffee powder, a half cup of coffee once, twice, sometimes more.

                On March 19, 2021, I corrected the mathematical language for probabilities (probability fractions) column labels, in 5-dice combinatorial space traverse layout pages, to "odds in 1", previously "odds to 1" (incorrect in "odds to" logic for the column items, coyly correct for the odds in/of one to add to one over the span of a probability fractions column, "odds [adding] to 1", cheeky column label).   Probabilities, probability fractions, odds in one, odds of one, prob., pieces of chance, chance fractions...
