In reply to M3EYP:
Dear Hans ans Jimmy!
Yes you can far away from any summit when activating as long as you are within 25 meters of the summit.<<<
In order to be unambiguous, let me put this in a different way!
The 25 metres rule refers not to a physical distance (QRB) between the actual peak and the location of the activation but in altitude! To be more specific, let’s assume that the peak is of X metres altitude. Then, in theory, draw the altitude line X-25m on your map. This area, of course will contain the actual peak you want to activate as well. Supposing that the activation is within this area, the activation is considered as valid.
However, the rule provides this kind of liberty exclusively for the case of physical obstacles, like precipices, steep and/or dangerous hill slopes, brushwoods, fences, etc. disabling the activator to reach the actual peak. That is, whenever it’s possible, the activator shall be at the actual peak or at least be as close to that, as it is possible considering the specific terrain, security, legal, proprietary right, etc. circumstances.
I hope, my interpretation of the rule is correct and clear.
Happy new year, good activating and chasing for all of you!
