Ball possession - how comes ?

[Tactician]

Played a CHL match today I was home and we both spec also teams were equal
I had 60:40 poss advantage till 20 min when friend of opp joined...posession changed to 58:42
When he scored for 0:1 i changed pressure to high and tackle to normal...also stoped clicking poss and clicked att bonus instead...possesion stayed the same 58:42 till end...
Won the game tho xD

Probably tactics influence possesion alot

Yes, especially when 'tactics' do not make any sense anymore in this game as such.
