You have to factor dropping points in along the way, so with the 8 fixtures remaining I think 14-15pts (out of a possible 24pts) would be a realistic minimal target. The real question is whether or not 71-72pts would be enough to get us in the playoffs...so you have to start asking will 2 of the following teams get the following number of points or more:
Boro: 13-14pts (9 games to play)
Preston: 14-15pts
Derby: 15-16pts (9 games to play)
Bristol: 16-17pts (10 games to play)
Wednesday: 16-17pts
Forest: 17-18pts
Hull: 20-21pts
Blose: 21-22pts
Over to you footyskillz...I look forward to seeing your analysis! Have fun 
Just like I don't see Middlesboro poor form continuing rate of 1pt per match average meaning finish if 67pts
I also don't see the Preston north end continuous hot form in last 8 at 2.5 pts per game equalled for the final 8 matches. They would achieve -77pts !
Middlesbrough matches home 5 away 4.
70-72pts
70pts if they match the average season pts per game 1.57 = 12pts
And I've included boros home and away avearge after mentioned poor form points per match wanted another measurement for forecasting (this is because that 1pt a match is pretty hopeless and really ? Are they just going to collapse to that poor form for another 8 matches?!)
Boro 72pts. From expected home average and away average 14pts
Home average points 1.5 (X5)
Away average points 1.63(x4)
Preston 69pts-77pts 69pts Matching Season average 1.5 = 12pts
77pts matching current form
Preston need to maintain their great form and would be a real contender
Derby county 66pts -68pts66pts If continue current form 10pts
68pts On Average pts per match for season =12pts
Bristol city 69-70pts69pts On current form 13.8 pts - 14pts
70pts On season average = minimum of 15pts
Bristol city are a real contender due to 2 extra matches. Thank fully Boro and Bristol city play each other !
Sheffield Wednesday 66/67 pts - 71pts71pts equalling current form =16pts
On season avearge=11/12pts
Wednesday need to continue to maintain their current form if so they are a real contender but can they maintain this form ??
Nottingham Forest 65/66ptsEqualling current form =12pts
On season average= 11pts
Summary -Forest would have to improve form and on points from season
Hull City 59pts-62pts 59 Current form 8pts
61/62 Season form 10/11pts
Hull have to super perform to get anywhere near
I'm not interested in Birmingham city the irrelevant!
Boro , Preston , Wednesday and Bristol City could all hit 70+pts based on this. For me I see Boro to get to the 71pts+ the other clubs need to reexamination of their fixtures for forecast
I feel Boro form could rise and Wednesday and Preston slow down .Bristol city are very interesting but then you bring in their fixtures and they are challenging .Conversely Derby fixtures less so. That said of all the clubs in contention some of these teams will pick up form and some will drop off . It's a potential indication but it's also noting fixtures of the opposition and also looking at home and away averages too for further indications.
