Spacing between Variable and Subscript in Formula

I need to have subscripts attached to variables but am seeing some odd outcomes in terms of spacing between the variable and its subscript.

So, something like x_{1} looks just fine whereas things like V_{p} and x_{pt} have too much space between variable and subscript. Attached file provides examples of what I’m seeing.

Any advice appreciated.

It would need “font-kerning” or “letter-spacing”, but both are not available in Math. You cannot do anything about it.
