First time using drybags

[Mark]

Well, I have started my dry aging and I went with the scotch fillet.
I am on the 11th day today and I am taking a picture every day, I will also weigh it every 10 days to see what is going on. I plan on aging it for 45 days, but then I read you go to 30% weight loss. Is it better to go by days or by weight lost??
At this stage the meat is losing 50g a day (500g in 10 days) but by my calculations my 3.5kg of meat should end up at about 2.4kg.

Thanks,
Mark.
