How is it possible that with 50 reads a week my research index only goes uo with 0,2 instead of 2,5 (50*0,05)?

The way this index is counted does correspond with the way researchgate says it is counted. I have 1800 reads this corresponds with at least 1800*0,05 = 90 But my score is only 54,7 Explain???
