The forecasting model behind the scenarios

Indeed job-posting indexes (Feb 2020 = 100) for the Australian sectors that technical program managers draw from, plus overall hiring in six US tech metros, with six-month scenarios that are backtested against a simple baseline.

An index of 126 means 26% above its own February 2020 level, not 126 ads. Sectors are broad (e.g. "Project Management" includes non-technical roles), so these are not counts of TPM vacancies, and GPU/AI-infrastructure TPM cannot be measured from this data.
