'systematically-decided' originates from the combination of 'systematic' and 'decide', where 'systematic' comes from the Greek word 'systēmatikos', meaning 'pertaining to a system', and 'decide' comes from the Latin word 'decidere', meaning 'to cut off'.

'systematic' evolved from the Greek 'systēmatikos' through Latin 'systematicus', and 'decide' evolved from Latin 'decidere' through Old French 'decider', eventually forming the modern English word 'systematically-decided'.

Initially, 'systematic' meant 'pertaining to a system', and 'decide' meant 'to cut off', but over time, 'systematically-decided' evolved to mean 'determined in a methodical manner'.
