I have solved mostly upto 1300x ... was able to solve a 1300 rated problem by 30-35min (sometimes 10-15 min if easy pattern) , so now i started solving 1400 rated ones, its been some days only but i am finding them a bit hard, had to see editorial/hint for almost all i solved (only 7 yet though) ... They are very observation based ig but i jump quickly into construction and coding as soon as i think i framed an approach.
