chalk.bar — predictive analytics for powerlifting training and competition, built on the OpenPowerlifting corpus of competition results. Where most tools assume a standard athlete and apply the same tables to everyone, chalk.bar starts from a weak population prior and lets each lifter's own data update it — strength estimates with honest uncertainty, meet projections, and on-the-day attempt support.
