I, personally have received 70 points as maximum and 45 as minimum till date for the blogs I have published ...
It also depends on whether you are publishing photo blog or video blog or drafting a travel blog of your travel ... and also on the quality of photos you select and also on the clarity of the subject you have chosen ...
Happy Blogging and Happy Travelling Bro!!!
