Other lower rank members might be thinking that's this formula is going to work again but it's not going to help you too so work hard on your posts  . This magic works once in long time or say in rare cases.

But these 2 days were lucky for the @OP as he gained 68 merits(64% of total) in these two days from high rank members and helped him to push the rank aside from 32 merits in the @OP post and it is because he has some quality posts also on his side.

So now keep in mind how the merit system works because now you know it and congratulations on your full member rank.
