+1 Speed Keyboard Escape treadmills are reported as training objects that can support Speed building, but the checked sources do not verify exact gain rates or best-value rankings. Log your own result and keep the comparison provisional.
The reported role of +1 Speed Keyboard Escape treadmills
Recent coverage describes +1 Speed Keyboard Escape treadmills as another way to train or build Speed alongside the keyboard route. That is a useful player question, but it is not the same as a verified formula. The source set does not provide a stable Speed-per-second value, item cost table, or universal best Treadmill.
How to log a training session
Use the same account and version when comparing a Treadmill to normal movement. Record the starting Speed, the time spent, the visible end value, and whether any multiplier or item was active. Repeat the observation before calling it a result. Do not use a one-off change to claim a global rate.
If you need a quick plan, use the Speed Session Planner and choose “Build a Speed buffer.” If a stage is the real bottleneck, return to stages rather than buying or equipping an item just because a guide calls it best.
What stays held
The +1 Speed Keyboard Escape treadmills page does not publish exact rates, a value ranking, or a complete object catalog. Those details belong in a future update only when tested and sourced.
