When i re-worked my blocks from this
To this
I had to deal with a lot of troubles:

so for my blocks with windows, as exemple, after changing dimensions i had to re-align the window at center:
I still have to work with positions like 11m75 or 11m5 or 11m25 (which is not really helpfull with increment)

It is the most important thing i can share:
Get good dimensions, Be lean, be clean!
