A saved score matrix ranks fixed assistant profiles
Read the explanation
The page scores five saved assistant profiles by adding a base score, task weight, priority bonus, constraint adjustment and ecosystem bonus. The default profile is long documents, depth, token caution and an agnostic ecosystem. Its Claude weights are eighty two plus sixteen plus six minus eight plus two, summing ninety eight. The default fixture replaces that total with ninety six. At three pixels per point the computed bar measures two hundred ninety four, assigned default two hundred eighty eight and difference two six. This is a saved illustrative score matrix. It makes no model request, measures no capability, and its older vendor labels are not evidence of present product performance. The same fixture assigns five sorted scores: ninety six, eighty eight, eighty four, seventy two and sixty four. The top score exceeds the runner up by eight points. At three pixels per point the top bar measures two hundred eighty eight, runner up two hundred sixty four and gap twenty four. Outside this exact profile, scores are bounded between forty and ninety eight before rounding and ranking. Positive constraint adjustments can raise a score even though the field is called a penalty. These displayed percentages are assigned fit points, not success probabilities, confidence intervals or measured reliability. Changing a selection recomputes this saved arithmetic and does not connect to any vendor service. Changing Claude to a Google ecosystem changes its ecosystem contribution from plus two to minus four, a six point reduction. Because this leaves the special default fixture, the new total is ninety two rather than ninety eight, while the displayed default was ninety six. At three pixels per point computed original ninety eight measures two hundred ninety four, new ninety two two hundred seventy six and six point ecosystem effect eighteen. The visible change from ninety six to ninety two is only four because the override disappeared. Native task buttons, selects, reset and text export package the chosen profile and rankings. That brief reproduces the sites own recommendations, not a current independent assistant benchmark.
