Hours needed to plat ?

[ahmedelebiary]

I feel like the 60 stated in the trophy guide is too low for the plat..I'm close to 50 and I still need A LOT of coins and equipment to buy (nearly most of the licenced and normal) racquets .

So for the dozens of people who recently got the plat, how many hours did it take you ? And what's the most effective and efficient way to grind coins with one console and controller ?

im almost done and im sure il be looking at about 80+ hours . I messed up and spent a load of coins on nike tops that you dont need though so maybe 60-70 is possible if you are efficient with the coins
