Connection line 5 and 6 at Kirsche Flubtern

Very often I use the line 5 from Bellevue to go up to Zurichberg. Most of the time the line 5 gives way to line 6 before Platte, the line 5 even stops for a while to let the line 6 go ahead and therefore one misses the connection at Kirsche Fluntern. This is totally ridiculous and frustrating!!! I am sure with a bit of better planning and common sense from both drivers 5 and 6 this situation could be avoided most of the time.
