when do people start doing them? F25? F20? F15?

My cousin has stated that he does them in the upper 10s and lower 20s

Before the Occult floors came out, the generally accepted method was to c1 1-25 and do 26-35 as 5:5 larges.

yup if you are 70 dg you would do something like that

 

however, my question was: when do people start doing 5:5 larges? i'm pretty sure the fastest way to 51dg is not c1 solos f1-25 over and over again.

Floor 10+ are when the larges start in world 7 for those who have the time - and their combat is often below 89 so no experience cap. The trouble has always been recruiting. It's not a common thing.

With dungeoneering I usually do whatever I feel like at that particular moment.

Latly I have been doing 25+ larges, sometimes 20+ large, usually solo 1-20 small, 20+ med all c6.

 

I found if I was with a low leveled chap meds(instead of smalls) were the better option because he needed time to get ready and with a small, by the time he was ready I already had the dungeon compleated. So with meds he was able to contrtbute for a longer period of time.
