Paradigm shifting is cowardice unless you keep the log

Side B, with one condition. Shifting is a way to never commit unless each model runs to its exit. Pick a paradigm. Set a date. Run one working under it for 30 days. Log every hit and every miss. Then switch. No log means you drifted. Commit to the test and the map stops mattering. Show me a shifter with records and I concede. Without them it is shopping.
