Here is some data related to eco of synch chips (not all of them)
(i hope this will clear things out a bit):
All known chips (up to XIV) can use NeoPsion 10 implant (most eco one, avaible at TT) so i consider person will be using this one (as an eco maniac).
Also i will consider that ME costs 135%.
Chip I (L): (i bought two of them at 126.32% so i consider it is avaible at this price from auction)
Chip decay: 0.900pec * 126.32% = 1.137pec
ME used: 1.800pec * 135% = 2.430pec
NeoPsion10 decay: 0.457
Total cost per use: 4.024pec
Time duration of buff: 300s
Cost per sec: 0.01341... pec
Cost per hour (considering person is whole time buffed): 48.288pec
Chip II:Chip decay: 1.200pec
ME used: 2.400pec * 135% = 3.240pec
NeoPsion10 decay: 0.457
Total cost per use: 4.897pec
Time duration of buff: 340s
Cost per sec: 0.01440... pec
Cost per hour (considering person is whole time buffed): 51.850pec
Chip V:Chip decay: 1.900pec
ME used: 3.800pec * 135% = 5.130pec
NeoPsion10 decay: 0.457
Total cost per use: 7.487pec
Time duration of buff: 390s
Cost per sec: 0.01919... pec
Cost per hour (considering person is whole time buffed): 69.110pec
Chip XIV:Chip decay: 4.000pec
ME used: 8.000pec * 135% = 10.800pec
NeoPsion10 decay: 0.457
Total cost per use: 15.257pec
Time duration of buff: 600s
Cost per sec: 0.02542... pec
Cost per hour (considering person is whole time buffed): 91.542pec
Other chips are proportional to their level and fit into the graph of eco. Those i used myself so i can write about them here
.
Observations/conclusions:
As you can see if you do not consider "strength" and "uses per minute" (that make it easier to concentrate after the buff is gone) as a factors then it is best to use small chips (I (L) and II) because they are much more eco. Small chips have another disadvatage - you need to take more attention to be buffed all the time because of the duration (I (L) needs 12 usues/h when XIV only 6 uses/h). Also remember that when you die with buff - it dissapears so less duration on you = less chance of loosing some of the buff - advanatge of small chips.
But in my opinion that ~40pec/h difference makes the small chip much more usefull for newbiee players. As a "synch gifter" it would be nice to give XIV buff to others though
.
Another thing: i really see no point of having the buff when sweating or sweat hunting in teams (mob will attack one member anyway so others can sweat normally, with 3 people the "conc lost" yelow lines barelly appear). So basicly those are perfect for solo sweat-hunters and from my experience it is worth of having the buff:
when solo sweat hunting combibo youngs i used to get ~400/h, now i am getting ~600/h with additional cost of 48pec (i use I (L) for now). Counting extra sweat at 0.3 (!!!): 200 * 0.3 = 0.60ped. So getting 0.12ped more per hour
. Not much but it is definetly way less annoying if you do not loose concentration + by using the chip you can get psyche, concentration and telepath skills
(not sure if mayby more).
Just small calculation
