Research time & speed-ups

How long a Lab research plan takes with your Research Speed, with the technologies it requires, what it costs, and how many speed-ups or Diamonds finish it.

How it works

Every research has an Original Time, set by the level it reaches. The research window shows less: the Original Time divided by 1 + your Research Speed, and divided again by 1 + 15% while the return-player Tech Investment is on, rounded down.

Research Speed is every source added together, as the attribute list shows it; the game's own list of sources is under Research Speed below. Type the total in, or open "From your research window", enter the Original Time and the time shown for any one research, and the page works the speed out.

A technology waits for the technologies it requires and for a Lab level, so the plan includes every research they still lack. Under Requirements, say what level each required technology is at; untouched, each is one level short, so only its last research is counted.

The Lab researches one technology at a time, so the plan runs one research after another. The Lab must be built (Warden's Office Lv.9) and not be upgrading.

Alliance help takes seconds off the time left on each research, for each help up to the number of helps. The Communication Center sets the base and the alliance technologies add to it.

"Use all" spends your Research Speed-ups first, then your Universal Speed-ups, the biggest that fit first; the time still left costs Diamonds, rounded up for each research.

Requirements

The plan includes the research these technologies still need. Set the level each one is at now; untouched, each is one level short.

Each research level needs a Lab level. Steps that need more than yours are marked in the plan.

From your research window

Open a research window and type its Original Time and the time it shows. The page fills in the smallest Research Speed that gives that time, with Tech Investment as ticked above.

Where Research Speed comes from, as the game lists it:

  • Upgrade Lab
  • Scholarly Pursuits
  • Alliance Research: Tech Exchange
  • Upgrade Inata's skill Grand Wisdom
  • Upgrade felon White Wolf's cell or grant yard time.
  • Apply for Position: Director of Justice

Enter the speed-ups you own. They are spent research by research in plan order, the way "use all" does in game; what they leave is paid in Diamonds.
