Thank you for your efforts,
Solo.
Unfortunately, in previous years, there also appear to be several days without an update.
Especially in 2017.
So I tried a different approach.
I used the scroller bar in birdmap.
I know it is not always 100% accurate, but it is accurate enough for this purpose.
In 2017, Karl flew 15 days between Syria and Estonia. (from 20.03 until 04.04)
In 2018, he was on the road for 14 days to fly this traject. (from 25.03 until 08.04)
I think we can conclude that Karl - if everything is fine with him -
can probably be expected in Karula Park around the 12th or the 13th of April.
29.03 + 14 (or 15) days = 12.04 (or 13.04)
So still 9 or 10 days to go!
PS:
A remarkable fact is that
the average daily flown distance was almost exactly the same (on this traject) in both years.
219 km/day in 2017 and
218 km/day in 2018. (rounded numbers)
2017: 7187 — 3902 = 3285 / 3285 : 15 = 219 km/day
2018: 7252 — 4205 = 3047 / 3047 : 14 = 217,7 km/day
