LETS DO SOME MAFF BOIS.
That's 12,111,575 xp solely from yews & 804127.5 xp from willows.
Now lets take a look at this scripts date of March 15th, 15 days ago. Yews are noticeably slow xp/hr initially then there's an upward scale in XP/hr capping at around a liberal 40k xp/hr. Now for estimates sakes we all know 1/2 of 99 is 92, so from 60-92 is 6,243,511 xp. If we scale the xp/hr down to an average 30k/hr, from 60-92 it would be 208 hours of gameplay. From 92-99 it would be the remaining xp of 6,517,178. Now we can consider WCing at a higher XP rate of around 40k/hr, that's 163 hours. 163 + 208 = 15 1/2 days using this script, pretty much exactly using the script since its inception without breaks.
Was this all from this script sir?
