The run-down time is also influenced by the pods themselves. For example, I have pads that take longer to finish the espresso, but others that take less time. But I find 50 seconds very long. Normally, the run-down time for me is about 25-30 seconds with Borbone pods.

I'm sure it depends on the pads, but it seems a bit long to me.
Have you seen that you can turn the metal part above the pad?
-->If necessary, turn it a little to the left (then it will be "stricter" to squeeze, but less/no water may run out the side...").
Caution: It is very hot when you turn when/after the machine is in operation! Therefore, it is better to turn it about 2-3 cm when cold and try whether it is better. If it becomes too hard to squeeze, turn it back a little...
