The last 2 weeks my opponents have been 1793 and 1748 respectively. I unfortunately only mustered draws in these rook endings.
Round 6
The final position has some play in it, but black has to make an opposition/triangulation mistake against the b pawn for their to be any real chances. I offered the draw in a very very slightly better position.
Round 7
I offered draws twice. Can't remember the move numbers. I think my opponent assumed I was crap at endings because of last week's early offer. Several much stronger players were surrounding our board after the pawn sac on b6.
