One of the compstars on the chart 12616GII is HIP101316 or 000-BCL-749.  According VSX is this a SR and variable between 7.05 - 7.3.   Why is this used as a compstar?

Hip 101316 is the comparison

Hip 101316 is the comparison marked '71' to the SE of the Nova. I am wondering has any recent V photometry been done on it.

I did use it on my last visual estimate. There is another comparison '71' to the NE of the nova can can be used instead.
