Share value (not $)

Hi all,
so I’ve been mining a little bit since last 5 weeks, and started to read trying to understand a bit better what I was doing.
went from 60MH/s rig to 340MH/s so I was comparing results on the process.
I understand I’m getting less valid shares now because of the increased difficulty based on my rig’s hashing power.

Now if I understood correctly, more difficult shares are more “valuable”, but that’s nowhere reflected when you look at your stats - you only see valid/stale/invalid shares.

I guess now the expected earnings - in crypto - are the reflection of that, but although you can project fluctuating $ earnings based on the crypto market value, can you link your share rate with your expected crypto earnings (based on network difficulty? reward value ?)

Cheeers !
