The exact weighting is part of the model we keep private (see methodology), but every number above is this trader's real, calculated value at that step.
The best single trade in this window was +$3,929 on "UFC 330: Charles Johnson vs. Jose Ochoa (Flyweight, Main Card)" (a 38% return). Every resolved position in this window closed in the green -- no losses to report. That single trade alone accounts for more than half of this trader's total realized gains in the window, worth keeping in mind when weighing consistency.
