Last 10% of bug fixed, 90% of total effort. I'm with you. This COVID-19 thing has changed my perspective on work, (although I'm not so sure about my employer's.) We're split into A/B team, one week in, one week out. I really happy, probably the first time in my working life I've achieved the nominal "work/life balance". The office feels more productive, I'm more productive, fewer people making ad-hoc demands on my time. The project is more focused if you make allowance for some handoff gaps. I'm not completely destroyed on Friday evenings, and if I am, I have a week to recover. I look forward to my ON week Mondays, I have had a week to think about what I could/should do. Really, if this continues with some adjustment, I think it would be the perfect cadence.
