a very small deflation upon scoring

Toast

hi,

    Can I check if a properly proofed dough should not deflate at all upon being scored? Mine just deflates a little bit (less than 0.2cm I guess),I'm wondering if this is acceptable? 

     thanks!

Acceptable? That's up to you?

For me, I prefer no collapse. But then I always work the gluten to it's maximum, so that I can rise to triple volume, slash and retain the gas.
