Hi OK465,
I 'spect the SOIA procedures to SFO 28L & 28R would be a little nerve wracking for you.
Those were perfectly OK since we were both locked onto separate parallel Localisers. From memory - if we went around from those approaches - don't we change onto diverging headings?
When the aircraft ahead was slower to line up & take off than the controller expected, we were both on the same runway track and visibly closing.
