This is strange . I have just done 4 speed tests with 3 companies and leaving my V.P.N. connected .
test my.net Download = 59.5 upload 5.5
race Communications , Download = 148.8 Upload 71.4
Fast , Download = 190 Upload = 110
Ookla , Download = 172.48 , Upload 78
All tests at the same time , what a variance . I am with 3BB and they use Fast.com for speed tests .
