@ angus25.
first of all, we welcome you to the thread and the community as a whole.
we are pleased that the 20 steps helped you maximize your speed which now is in a range closer to what you pay for and what you are supposed to get in the first place.
the reasons for your sustained DL and increased UL are:
1) the tweaks work
2) you speed tested in a time of the day when there are more users in your access point who are downloading than uploading.
here are my suggestions:
1) observe the stability of your speed for one week, speed test at least 3 times a day (early morning, peak hours in the afternoon or evening and at dawn), post your speed.
2) try to increase your RWin to the "value of 8" if it increases your DL.
3) regularly clean your pc.
Hope that will help.
BTW, if the tweaks worked for you, please visit and bookmark http://coolbusteratyourservice.blogspot.com/
