vmandr,
clear,
important i think to keep in mind that there are such jumps ... and other 'anomalies' that are related to the tool,
i dont know the extrapolation algorithm used by FR24... next to jumps there are also very significant turns that you would not expect ... if you look at the North Atlantic for example, you can see a plane symbol ('inside' the purple line, so not on a changeover point from a "loss of coverage ---- line" to a "solid purple line") ... change heading in an instant from say 270 to 0 and shortly thereafter to 180 before turning to 265 ...
so be careful with interpretation is the message,
