Meaning of "ためし" in this sentence


> 驚くことはないよ、私なんか彼女が理解できたためしはない。

What i understand is : "It is not surprising! I, somehow, am unable to
understand her" ?

The only 2 "ためし" i found are : 試し. trial; test​ and 例. precedent; example​ But
i can't see what it would mean..

Thanks everyone !




There's another ためし that fits here. Etymology from Shogakukan's 国語大辞典:

> ためし【例・様】  
>  （「た」は「手」で手本、「めし」は見せるものの意という）

Definitions and pitch accent from Daijirin:

> ためし [3] 【例・様】  
>  （１）それより以前に実際にあった事柄。れい。先例。前例。「そのような―はない」  
>  （２）手本となること。また，故事。「老たる馬ぞ道はしる，と云―あり/平家 9」

This has the same pitch accent as 試し, so verbally and in kana, you'll just
have to know both terms and figure it out from context.

Since ためし in the sample sentence would mean "past instance of something", and
since there aren't any past instances of 理解できた, a better translation might be:

> That is not surprising. I ~~do not always understand~~ **have never
> understood** her myself.
