I think I'll scrap the countdown timer. My program is a multi liquid filling program based of recipe, then self cleans then mixes the mixture to time again set from a recipe. I was wanting to add recipe progress tracking and then display it as a percentage. Having a think about it today I'm thinking to split each section up, track each with a timer/counter then convert them to display an overall percentage eg when liquid section is at 100% the full job completion might only be 40%
