Counting Wilt Chamberlain's Steals, Blocks, and Turnovers

Basketball Reference has started listing some game totals for steals, and blocks before they became official NBA statistics.  They actually list Wilt Chamberlain as having 446 blocks for the 1972-73 season.  How accurate is that total?  I can't watch footage from that regular season to know how accurate it is, but I can get some footage from throughout his career to try and see how often he got those stats that weren't kept by the NBA during his career. How often did Chamberlain get steals, or blocks?  How often did he turn the ball over?  I don't want to see highlights.  I want full games.  

There are numerous problems that I ran into.  Finding full games from his career is tough.  I settled on a full quarter for 1 game, and a full half for more than 1.  Another game shows the first 3 quarters, but doesn't show the full 4th quarter.  When it came estimating how much time in a game was shown, or how much Chamberlain played in the footage, one issue was the lack of an onscreen clock.  It was rare for them to put the time remaining on the screen back then, so I found myself depending on the announcer to say how much time was left in a quarter.   I can't see everything, especially with the lower quality of the footage.  In Game 5 of the 1973 Finals, Wilt was given credit for 8 blocks.  While the ending of the game isn't shown, a graphic says that he has 6 blocks, and he picks up another on in the game footage I have, so that would be 7 blocks in the estimated 43 minutes of game time shown, but I only count him as having 4.  I went back, and watched it again, and I still have him with 4 blocks.  I wonder how did they have him with 7 blocks up to that point in the game.  What were the unwritten rules for counting blocks before the NBA made them an official stat?  Only one of these games is from the regular season, so these stats probably don't represent what did in the regular season.  This shows more of what he did in the playoffs against quality opposition.  Playoff game also tend to be played at a slower pace than regular season game. Below I have links for videos, and time stamps.  This video usually come from late in career, while he was with the Lakers.  I still think that relevant since Basketball Reference list Chamberlain with 446 blocks in the 1971-72 season.

The thing that stands out to me are turnover numbers.  Most of the footage is from late in his career when he didn't touch the ball that much.  In his peak scoring years, he likely turned the ball over more than anyone else in NBA history.  He probably had numerous seasons with more turnovers that the official NBA record held by James Harden.  This is an ongoing project.  I would like to be able to look at other games. I may at some point try to come with estimates for steals, and blocks per 100 possessions in his footage.  I may also factor in field goals attempts, and assists to try to come up with an estimate for how often he would've turned the ball over.
