You missed some of the best bits:
Not only fuzzy satellite photos and guessing where people are but:
Scale 1:250.
Alot of features covered by foliage.
A cursor that is so tiny the datum points will be a bit hit and miss.
The notion the measurement is accurate to within 20mm ?
I suppose words like "mensuration" and "metrology" are missing from the vocabulary.

see section 3 of linked document.
There are lots of pretty sketches and dimensions.
Excuses, excuses, excuses.
Throwing long words in to make yourself sound impressive, are you Alice?
Words not even needed in this particular situation as i suspect you know full well!
Immediately before (whilst the Mccanns were in PdL) the hedges were cut back.
At junction with the alleyway, the footpath actually measures 240 cm, but I erred on the safe side and called it 230cm.
I notice that you prefer to back Slarti who is stating the distance between Jane and Gerry was 30 cm rather than back the truth which was 120cm(+)
In English Imperial measurement this equates to:
1 foot against the potential for 4 feet.
So Slarti is trying to make out that Jane was only one foot behind Gerry as she passed him, whilst in actual fact, Jane had the potential to have been over 4 feet (away) behind him
That is a big difference in a situation like this.
Slarti, Alice, please stop trying to pull the wool over our eyes.
