is only playing 681 games in the last 4 months not enough?

Really? Why are you asking this question? This sounds like a humble brag coupled with attention seeking. I could be very wrong. I certainly am no saint!! But come on man!🤷‍♂️

The reality is after about 3 or 4 games, most people will start to see a significant decrease in their ability. Chess takes a lot of brain cpu cycles, it's easy to burn out. My recommendation is to play no more than 3 a day. That might improve you score a lot in and of utself

You would be surprised the number of contributing factors. Not getting enough sun during cloudy seasons. Skipping meals. Not getting quality sleep. Simply being angry can make your game suffer

Pride is probably the biggest barrier to improvement. I hate bringing this one up because I'm not the humble person myself. But it's just the truth
