Description

Welcome to the one and only Build Master(s) Corp, where I (BuildMasterCEO) make some experiments that many visitors have gone to, and have now effectively become wonderful test subjects of their own will. Oh also I guess I have a sentient AI that has led to mass confusion on what it is, with this AI being the Test Account (TA) which gathers information on many many things for both it and for me. Now, I do not plan on having jobs for people here, mainly due to that being a horrible waste of time and likely money for everyone, so if there are ranks like 'Employee', simply take it as a title rather than something that you must upkeep (basically 'bragging rights' if you will). Aside from that, the Experiments are hosted under the TA for now.

12 measurements spanning 78 days, net +39. Dots are measurements; the straight line between them is drawn to join them, not to claim we know the path taken in between — snapshots are recorded only when a count changes, so gaps mean “no change observed”, never “interpolated”. The vertical axis spans 100–151 and does not start at zero.
