Did a quick update of the chart in OP.

Added Latam, which has 2 qualification paths (making it more difficult to add to a comparison)
The 2 paths are either lower TP requirements but 100% on own metal or higher TP and 16 longhaul premium cabin segments on own metal. Both paths requires a certain spend as well.

While Latam offers no segment path to super-tier, the option 1 could cater to a commuter as it "only" need you to collect 1,75 times as many TP as a regular emerald.
However, the 130400 TP needed equals 1047 ARN-HEL segments in cheapest Y. But at least 525 r/t tickets HEL-ARN would meet the spend requirement (≈20 000€).


At BA forum there is a guide to GGL and someone was kind enough to calculate just how much flying 5000 TP is. If you are doing GGL by segments, you would need 250 longhaul segments in cheapest economy class.


To me, it is very clear that Finnair's segment qualification to Lumo is an anomaly. Finnair's 150 segments with no spend requirement makes Lumo a very very different super-tier than all the rest.
