Hey HoneyB - you are doing great for 6 weeks! I was also a member of the "slow bending and straightening" club - you will continue to improve if you are patient and don't do things that will aggravate and further inflame your healing knee. That exercise you described with the weight pushing down sounds like torture - I would definitely refuse to do that again. I was very fortunate to have excellent PT's who never pushed my ROM (I even wanted them to when I was frustrated by my slow progress) - they focused soley on functional movement - my gait, my balance, strengthening the surrounding muscle groups like glutes and quads to take the pressure off my healing knee. Walking is your friend (as well as lots of patience). I did not achieve 110 flexion until the 6 month mark and still don't have 0 extension at 11 months - but I can do all the activities I enjoy and am working to build my stamina. Hang in there!
