I want to express a possible result of an action that might have been carried on in past, but I don't have any idea whether the action is done or not. Consider this sentence:
If you'd read the book, you would know what I mean..
Given the fact that I have no idea whether the listener has read or hasn't read the book, does this construct work?
I want to imply:
- This is a strong condition, and I'm sure if the action is done, the result holds true.
- I have no idea whether the action is done or not, and I don't want to express It's unlikely that you have read the book. In fact, there is a high chance that listener has read the book.
My inclination is if I remove would in result sentence, it might feel better:
I you'd read the book, you know what I mean..
However, no mixed-conditional that I've found mention the last construct.
After more search, I come to this construct:
If you've read the book, you know what I mean
I think the use of present perfect is more natural and may suggest that this action is possible. Does it? Anyway, I don't know in which conditional categories this falls into.
