It's been a tough day at work. 99% my calcs are likely a bit wonky Should be able to calculate a more accurate ETA when she sets off and gives us an average speed to work by.To quote Mr M’s post of 9pm yesterday ‘I originally estimated an arrival around 17 Jun but that has already slipped to 18 Jun now. She could make up time but I will adjust the ETA when I see what speed she resumes her voyage at.’ Looks like you both have the same calculator but depends on how quickly she responds to her suckling at Singapore.
