The research behind the model
Deloitte and Google's Milliseconds Make Millions study measured a 0.1s mobile speed improvement driving +8.4% retail conversions; Google/SOASTA found bounce probability climbing 32% as mobile load goes from 1s to 3s. This model applies a deliberately conservative per-100ms coefficient with diminishing returns as pages get faster — treat the output as a floor for the business case rather than a ceiling.
