Every machine sized a like account in a like state to the same position as every other person's, so two people's positions could match to the unit. Each person now draws a size factor in [0.85, 1.15] per trade date, seeded by the master's uuid for them; all of one person's accounts share it. The factor moves the hold a DXtrade leg is sized for (hold / factor², since size goes as 1/√hold), so the instrument pick, the dashboard's next leg and the Firms page's reach test all see the hold the size was made for.
