I have made a graphic (because it is too much text) which calculates the Qpost plus 111 days.

It also indicates if:

• a [marker, square brackets] was used

• if the word "phase" was used.

"Phase I" was mentioned in Qpost# 243 on 2017-12-01

"Phase [2]" was mentioned in Qpost# 797 on 2018-02-21 and Qpost# 819 on 2018-02-23.

This is to help people test the theory.
