Didn't take your advice, and at first I regretted it.
I decided to spend about 450 gran and even after recycling a bunch for about a total of 60 or so pulls all I got was 1*s and about 3 or 4 2*s.
I was doing one card at a time though, which was stupid I guess. Decided after that to do it all at once with my alts and I did way better. Did probably around 250 pulls and got 4 5*s, about 10 or so 4*s, and maybe dozen or two 3*s and two*s each.
Sorry I didn't keep exact numbers.
