I agree with the basic concept of calculation according to filter. To some extent, this is already happening. If you look at a S2S log in the Database, this correctly gives the points to the first listed activation of the year and the first listed chase of the day. These QSOs may not have scored points in the main tables if they were not S2S QSOs.
So it might be possible if the “filters” actually didn’t filter, but linked to other pages that each scored the activations with their individual/independent logic, rather like the S2S honour roll.
However, with 24 bands and 6 modes, this would potentially give rise to 144 pages. That’s before multiplying by how many years we have had if you want that filter, or by the 2846 activator for their individual filtered scoring.
There’s probably a neat IT formularised way of generating these webpages. But is it worth it? If it can be done cleverly and efficiently, then yes. Until then, no.
I strongly feel that there should not be any recognition in the number of QSOs made, or length of time spent on a summit in the activator’s credit. As it stands, an activator need only spend a short time doing radio from a summit. This is good, it is sensible. As it stands, any activator who stays longer and makes large numbers of contacts does so for no gain other than the enjoyment of what they are doing - and I think that is the best reason.
Clearly, the rules do not discourage people from making lots more than 4 QSOs. In the whole life of SOTA, the average number of QSOs per activation is 18.3. That is astonishing given that the rules say that you only need make 4! And this is an average taken of over 97,000 activations! That is surely powerful evidence that activators need no encouragement to work more than 4 QSOs.
And if activators want to switch off after 4 - let 'em! They are the ones who have climbed the hill, so they are the ones who choose what to do when up there. As Etienne says, there are good reasons to switch off like weather and time, and this is another reason not to “reward” extended stays. That wouldn’t be fair on those who had to make sensible decisions to go QRT.
In addition to wx and time, other “good” reaons for going QRT are preferring to sit and chat with a walking partner or family, not being in the mood for radio, or just being bored. All reasons are good reasons.
