请问教授这样回信算是平推吗？（想避免黑推）

我向一位教过我ML和java课程的老师要推荐信，他回复如下：

I'm happy to write a letter for you, though I can only really speak to your performance in my classes, which might not be as comprehensive a view of your abilities as you might want. Still, if you want me to, please send me your CV and information about your research interests.

请问这是平推还是黑推？我不可能也没想过要强推（毕竟只上过课），但希望避免黑推。

FYI. 这位老师人是那种很nice的，但也是公正认真到“死板”的老师。但我上了他两门课都是A，而且他的ML课对我申硕方向很对口，所以还是希望争取一下。
