I wouldn't worry about weight too much, while it's good to keep an eye on weight so you can easily spot any sudden gains or losses which may indicate a problem they rarely overeat so unless fed a lot of high fat treats they will remain at a healthy weight, my hybrids have probably averaged around 65g, some more some less, there is no real average.
keeping an eye on general condition & activity is a better way of monitoring how healthy they are.
