Visible boost labels
Gameplay shows Admin, Daily Streak, Items, Gamepass, Trail + Aura and Rebirth multiplier labels, plus Friends boost. They identify things to inspect in your game, but do not establish a universal stacking formula.
Compare measured gain
Take a timed total-Speed sample, change one condition and repeat the same activity for the same duration. Compare gain divided by seconds. Other changed conditions can explain a difference, so keep the test consistent. For example, a sample gaining 300 Speed in 60 seconds measures 5 Speed per second. A second sample gaining 600 in the same time measures 10 per second, or twice the first sample. These numbers demonstrate the comparison only; they are not built-in game rates. Use accumulated Speed for both readings. Comparing a movement setting with an accumulated counter will not tell you how quickly your total grows.
Timed x2 boosts
One shop view shows timed x2 boost options. Historical prices or durations in footage are not a current offer. Read the current shop terms and remaining time before extending an estimate beyond a boost window. Split a longer play session into separate measurements if a temporary boost will end midway. A ten-minute estimate made from a short boosted interval assumes that rate lasts all ten minutes. If the boost has less time remaining, the result can be too optimistic. Record another sample after expiry and use the new rate for the remaining target. A timer seen in an older video cannot tell you how much time your own boost has left.
Trail + Aura and new effects
A Trail + Aura row is visible in gameplay. The official event announces new effects but supplies no named ranked roster in the collected material. Read actual item descriptions when available instead of assuming every effect is equal.
A practical sequence
Record total Speed and time a repeatable activity.
Subtract starting Speed from ending Speed to find gained amount.
Change only the boost condition being compared and repeat the interval.
Compare gain per second and take a new sample when a timed boost expires.
If you get stuck
If samples differ unexpectedly, check whether movement, level or another boost changed too.
If shop terms differ from footage, use the current in-game terms, not the old screenshot.
Common questions
Do all multipliers multiply together?
A stacking rule was not established. Measure effective gain rather than multiplying labels as a claimed formula.
Which boost is best?
No universal best purchase is established. Compare gains and read current cost and duration for your own decision.
How much does Friends boost add?
The label is visible, but no fixed current value or combination rule is supplied here.
Can I reuse a sample after a boost ends?
Take a fresh sample; the earlier boosted rate may no longer describe your play.
