maximum number of “crosses” being five.

5.3.2.6 Target specification

Table 5.7: Target specifications table serves as a guide for the developers while reviewing and
improving the device. The ideal value is the set of values that we aim to achieve with MOJO to
fulfill user needs. The marginal values are the minimum acceptable values for each specification.
