I actually prefer that thereβs no time limit(other than 24 hours).
Most days I take 10mins ish Iβd guess but if I get stuck I actually prefer leaving it and coming back to it - I think there is slightly more skill when you have to think about it eg today.
I accept that many are more skilful than me anyway - as soon as I got close to an average below 3.8 I encountered a spell of 4s+ for a while. That top 10 place is beyond my means - hopefully still within Albionβs just possibly!
I normally do it in the time it takes to drink my early morning cuppa. I think there was one time (maybe two) when I left it and picked it up later in the day.
