Since that time (for 7 months total now), my alt has continued to explore and track the data. My exploration habits have stayed roughly the same: averaging roughly 2 sessions per week, I explore three and only three systems for sites and occasionally check those three again later in the day. She can fly a T3 quite well now, and though she makes most of her (/my) isk elsewhere (through trading--posts on that to come), she nonetheless continues to pay for a PLEX plus a few hundred million extra for pew from exploration. So, let's look at both sets of data:
-----> Pre-Odyessy (Jan 31 - June 4 / 4 months) - (apx 2.8b or apx 700m/mo)
Provisional Blood Outpost - 6 10m faction loot, 4mil, 1m (15m)
Mul-Zatah Monastery - 7 340m faction loot, 2m, 340m, 2m, 2m, 2m, 2m (690m)
Blood Outpost - 9 17m faction loot, 5m, 2m, 12m, 1m, 70m, 18m (125m)
Blood Raider Psycho - 2 80m (30m in faction loot), 75m (155m)
Blood Annex - 3 95m faction loot, 55m, 1m (156m)
Gas - 4 74m
Data - 55 695m (AV=12.6m)
Relic - 38 576m (BPCs 315m) (AV=23.4m) (Highest: apx 125m)
-----> Post Odyessy (June 4 - Nov 19 / 5 months) - (apx 4.15b or apx 830m/mo)
Provisional Blood Outpost - 4 70m,
Mul-Zatah Monastery: 7 25m, 5m, 190, 4m, 2m, 2m, 7m (235m)
Blood Outpost: 8 110m, 7m, 25m, 1m, 1m (143m)
Blood Raider Psycho: 10 60m, 80m, 40m, 400m, 80m, 200m, 55m, 220m, 280m, 75m (1.490b)
Blood Annex: 3 3m, 125m, 1m (128m)
Crimson Hand Supply: 2 50m, 50m (100m)
Data: 45 330m (AV=7.3m)
Relic: 42 580m (100m bpc) (AV=16.2m)
Belts: 170m tags / (since 7/29): 730m (900m)
Gas: 2 24m
Null: 1 Relic 41m, 1 Data 14m (55m)
[Extra PI: 200M per month since August 4]
-----> Post-Rubicon (Nov 22 - )
I will discuss this data in three sections: First, comparing my earnings during these two periods. Second, thinking about what exploration will look like in my third period, from Rubicon to the summer expansion. And third, focusing on how new players can best profit from exploration, post-Rubicon.
I. Odyssey, before and after
II. Exploration post-Rubicon
Rubicon will bring a number of changes to exploration, which will affect what my third set of data will look like months from now. First, Rubicon will likely further hurt the data/relic loot market, as new and returning players will be doing a lot of exploration. This market may recover a bit in the lull before the summer expansion, but for me, this means I probably will stop doing these sites unless I have little else to do. Second and thanks partly to the suggestions of low-sec dweller Sugar Kyle, the lower end DED sites in high-sec are going to spawn in low. I've prepared for this by training for an AF for my alt, and I expect to run these whenever I find them. I have no experience with them, so we will have to see what kind of isk they bring in once we compiled the next set of data. I'm at least very excited about new sites to run. Ghost sites will also add new content, although since my alt stays in an isolated area I do not expect to run these often, if ever (the current word is that there still be one per region spawning). Finally, my alt's skills continue to improve, and I am hoping she will make more off 6/10 sites in the future.
III. Exploration for new players, post-Rubicon
Based on my experiences thus far, if I were starting over as a new player and looking to get into exploration here I what I would do: I would find a suitable place in low sec or null to live, avoiding high sec exploration almost altogether (I hope to make a video series covering how to find good places to live in low and get started at some point in the future). I would skill first for scanning and hacking skills, running relic and data sites as well as low end combat in a frig (like a LM Kestrel). However, before training toward running higher end complexes, I would focus on getting into a stealth bomber and farming security tags in .1 and .2 space. This would likely end up more profitable than exploration until the 5/10 and 6/10 sites could be run reliably.
Hopefully this data has been useful. If anyone else has any stats of their own, especially different experiences than I've had or suggestions for where to focus in the future, I'm all ears.
