I choose to approach it more as a logic puzzle than as math. We do have details to go off of.
1) Dropping of pellets has an effect.
2) The DRC (Cyan) has stressed the the importance of consistency. Directly quoting, "The speed is not nearly as important as the spikes."
3) The light level has "been updated (raised and lowered) as necessary".
4) "The effects on the lake are subtle, and
they are not analog."
5) Changes happen when currently undefined "thresholds" are reached (and those thresholds are meant to be months apart).
It's true, those details don't tell us much. I think there are some reasonable assumptions that can be made however. First, that we do not have a linear system. Also, it seems hinted at that our actions in attempting to feed the algae can be detrimental as well as helpful. Can the lake be over fed? Do the needs of the lake change in response to other factors? Is, perhaps, the system based less on overall results than on average levels of participation? All of these are questions which could (I stress
could) be important to understanding the changes and what needs to be done.
At the end of the day though, the important thing to keep in mind is that, as RAWA said, "The journey is the reward". More than simply trying to achieve some uncertain goal, the biggest factor here should be that we, as the community of URU and D'ni, have been given a way to impact and change the state of the world. Our actions have an effect, and someone out there is paying attention to them. At least to me, the what is not as important as the how. We will see the end result of feeding the lake when it happens...if it happens. Weather there is an end to this project or not, the fact remains that it is an example of what we do, as a whole and as individuals, having
meaning. Even if that meaning isn't clear.
In a strange way, it can even be said that debating what we should be doing like this is as important to the process as doing it. Right now everyone here is interested and involved. You care about what happens. Everyone checking into this topic, in some way is investing a part of their self into what happens, and what the future holds for this. Think about it for a second, and tell me there isn't something magical in that.
