meaning of statement after , ,if'

[Saneta]

I signed the letter. Later my friend says about me, with the statement:
1.If you signed this letter, you made a mistake. - is it ok?, because I don't mean the conditional 2, but the statement: if you signed this letter.

An example of using conditional 2 is for example:
2.If you signed this letter, you would make a mistake.

Can: ,,If you signed this letter'' have conditional meaning as in sentence 2. and the meaning of statement as in sentence 1.?

Next example:
I stopped doing this and I did wrong. Later another person says about me with the statement:
3.You did wrong if you stopped doing that. - is it ok?

Thanks.

Example 1: "If you signed this letter, you made a mistake."
That means: If you have already signed the letter, (the speaker thinks) it was a mistake for you to have done so.

Example 2: "If you signed this letter, you would make a mistake."
That means: If you were going to sign this letter (now or later) (the speaker thinks) it would be a mistake for you to do so.

Example 3: "You did wrong if you stopped doing that."
That means: If you have already stopped doing something (the speaker thinks) you should have continued doing it.

All the examples are correctly written, but they mean slightly different things.

Do Alan, Torsten, Kitosdad, Mr Micawber agree to Beeesnees?
Thanks.

That should be "... agree with Beeesneees?" ;)

Beeesneees is a native speaker English teacher. At any rate, if I received such a detailed and laboured explanation from anybody, I would thank the anybody first instead of inquiring for confirmers.

[Beeesneees]

Thank you Haihao, you are very gracious, as always. However, I didn't mind Saneta seeking additional confirmation. After all, unless she's been following a lot of the threads, she had no way of knowing how accurate my information was likely to be.

Dear Haihao,
You are not very perceptive. I wrote ,,Thanks'' in my first message and it concerns thanking for the answers from anybody.
Of course I'm grateful to BEEESNEEES. Yes, I request for the opinion from anybody or all from the team of english-test.net and I don't hide it.
Regards,
Saneta
