I tell my patients it makes sense for them not to notice because in everyday life it's much more apparent big things they (still) can't do than the half-centimeter they improved since yesterday. Whereas I may not have seen them for two weeks so it's much more noticeable.Sometimes progress is slow and we don't notice that progress, a bit like my knee, progress has been slow but when attempting something I could not do a few weeks ago you realise the progress has been there just too slow to be obvious.
Painfree movement can help so much with recruitment and coordination and especially in the shoulder you have to have those in order to progress.
