I did wonder about starting a grass cottage and roading the copper before using both workers to finish the mine, then the chop can come in with the maths bonus, but several turns later, meaning the cows are ready several turns later. So we probably lose those ten extra hammers.
Alternatively road the copper and chop the forest, then using both workers to finish the mine means you don't waste a worker turn on cottaging the plains tile SW of Dunkirk.
Alternatively we do what you said originally...
I haven't worked out if either of those get our fifth city set up quicker, or how the forest growth changes that, but I might have time to test tomorrow.
