you could also look up a few posts in the thread that published cheap oneway or roundtrip fares on TK to use in the challenge.
Yes that is what I have been doing but some open jaws/multi city have a significant discount then when booking separately. And Google Flights multi city only allows you to search one specific day for each segment.
