Feasibility score
What it producesalso: feasibility · ambition and feasibilityAn honest 1 to 10 calibration of how doable an experiment is, from a standard assay with commercial reagents to technology that does not exist.
Nine to ten means a standard assay and one to three months; one to two means the required technology does not exist yet. Ranking weighs feasibility against ambition rather than optimizing either alone.
